- FIG. 1 it is obvious that there are several ways that the protective covering can be assembled around the shoe 10 .
- a representative way of putting on the covering is the following:
- the right and left flaps 24 and 28 of the toe member 14 are opened up as is shown in FIG. 4 .
- the toe (front part) of the shoe 10 is inserted into the toe member 14 with the spikes 20 being positioned over the bottom member 32 and the toe of the shoe 10 being positioned between the right flap 24 and the left flap 28 .
- the left flap 28 is then folded over the shoe 10
- the right flap 24 is folded over the left flap 28 and the two flaps 24 and 28 are fastened together by pressing the hook fasteners 36 into the loop fasteners 38 .
- the heel member 18 is then positioned around the heel (back part) of the shoe 10 with the sole of the shoe 10 resting on the bottom member 48 .
- the right strap 26 is pulled back towards the heel member 18 and the loop fasteners 40 are attached to the hook fasteners 50 on the right side of the cup portion 46 .
- the left strap 30 is pulled back towards the heel member 18 and the loop fasteners 42 are attached to the hook fasteners 50 on the left side of the cup portion 46 .
- the ankle strap 54 is pulled over the front of the ankle and the loop fasteners 56 are attached to the hook fasteners 50 . Again, the order of attachment is not important and the shoe covering can be assembled in other sequences.
- the protective covering once the protective covering has been positioned over the shoe 10 , it can be pulled off of the shoe 10 without unfastening the straps 26 and 30 , and then can be repositioned on the shoe 10 at a later time, without unfastening the straps 26 and 30 .
- the straps 26 and 30 are modified to produce a toe member 14 that is positioned around the shoe 10 in a slightly different manner.
- the straps 26 and 30 are lengthened so that they extend around the heel section 23 of the shoe 10 , and the loop fasteners 40 and 42 are replaced with fasteners that allow the strap 30 to be attached to the strap 26 .
- the patch of loop fasteners 40 is replaced with a patch of hook fasteners, and the patch of loop fasteners 42 are moved to the other side of the strap 30 so that the loop fasteners occupy the region outlined by the stitch pattern 63 shown in FIG. 2 .
- the straps 26 and 30 are pulled around the heel section 23 and hooked together using the hook and loop fasteners on the straps 26 and 30 .
- This embodiment eliminates the need for the heel member 18 , and can be used in situations where the protrusions 20 only extend from the front part of the shoe 10 . However, even in this situation, it is preferable to still use the heel member 18 , so that the front and back of the shoe 10 are both approximately an equal distance off the ground.
- the straps 26 and 30 are permanently fastened together, such as by sewing or by making the straps out of a continuous piece of material. The straps 26 and 30 are then pulled over the heel section 23 of the shoe 10 after the toe member 14 is positioned, thereby eliminating the need for the heel member 18 .
- the flexibility of the neoprene used in the construction of the toe member 14 means that a single size design of the toe member 14 can fit many styles and sizes of the shoe 10 .
- the toe member 14 and the heel member 18 are comprised of a flexible material.
- the term flexible material means a material that stretches to fit more than one shoe size.
- the ability of the right flap 24 and the left flap 28 to be pulled apart and opened up as shown in FIG. 4 allows one size of the toe member 14 to be used with several sizes and styles of shoe and makes it easy to position the toe member 14 around the shoe 10 . This is especially important when the shoe 10 has sole protrusions, such as cleats or spikes. If the toe member 14 didn't open up, the protrusions would catch on the covering as it was pulled over the shoe. This also allows a person to step into the toe member 14 without having to stand on one leg while they attempt to pull a covering over the shoe.
- heel member 18 is a separate piece from the toe member 14 also allows a single size of heel member to be used with several sizes and styles of the shoe 10 . It is also easy to position the heel member 18 over the shoe 10 and use the straps 26 , 30 and 54 to achieve a tight fit of the toe and heel members 14 and 18 on the shoe 10 .
- both the toe member 14 and the heel member 18 also makes it easier for the person wearing the protective covering to walk. If for example, a protective covering only covers the toe of the shoe 10 , then a person wearing the shoe 10 is walking on an uneven sole. However, if both the toe member 14 and the heel member 18 are used together, then a more even sole is achieved.
- the use of the front protective sole 60 on the toe member 14 and the rear protective sole 62 on the heel member 18 facilitates the comfort and traction of the shoe covering.
- the protective covering protects the protrusions 20 from wearing out prematurely.
- the protective coverings are positioned around the shoes 10 when the wearer is off the track or playing field and is walking on a hard walking surface, like asphalt, concrete, wood or tile.
- a hard walking surface like asphalt, concrete, wood or tile.
- it is the front bottom member 32 , and sometimes the back bottom member 48 , that protect the protrusions 20 from premature wear.
- the thickness and composition of the front and back bottom members 32 and 48 depends on the type and size of the protrusions 20 .
- regulating bodies usually allow a maximum of six spikes per shoe, and these cannot exceed a quarter inch in length when running on all-weather track.
- all shoes worn by sprinters only have spikes in the toe region, not in the heel region.
- a seven millimeter thick neoprene front bottom member 32 provides the primary protective cushion for the spikes to sink into, and is said to help prevent at least some of the protrusions 20 from contacting the walking surface.
- the front protective sole 60 provides a durable sole that reduces the likelihood of slipping and also provides some extra cushioning for the spikes.
- the back bottom member 48 will provide cushioning for these spikes, and is said to help prevent at least some of the protrusions 20 from contacting the walking surface.
- the back bottom member 48 and the rear protective sole 62 are preferably used so that the heel and toe of the shoe 10 are resting on surfaces approximately the same height off the ground.
- the composition and thickness of the bottom members 32 and 48 can be varied.
- Another reason for using the protective covering is to cover dirty shoes, such as muddy soccer shoes.
- Use of the protective covering keeps the mud mostly inside of the protective covering, thereby protecting floors, carpets, car interiors or other areas from getting soiled.
- walking surfaces such as floors, carpets, golf greens and other surfaces from damage by the spikes.
- Use of the protective coverings protects such surfaces.
Abstract
A two-piece covering for athletic shoes having spikes, cleats or other protrusions extending from the soles of the shoes. The covering comprises a toe member that wraps around a front part of a shoe, and a heel member that is positioned around a back part of the shoe. The toe member comprises two flaps that open up to accept the toe of the athletic shoe and a front bottom member attached to the flaps that prevents the cleats or spikes on the front of the shoe from contacting the ground. The heel member comprises a cup portion that fits around the heel of the shoe and a back bottom member attached to the cup portion that prevents cleats or spikes on the back of the shoe from contacting the ground.
Description
- This application claims the benefit of
provisional application 60/491,230, filed Jul. 31, 2003. - 1. Technical Field
- The present invention relates to protective coverings for shoes having spikes, cleats, taps or other protrusions extending outward from the bottom of the shoe, and more particularly to a covering comprised of a front part that wraps around the front of the shoe and keeps protrusions on the front of the shoe from touching the ground, and a back part that fits over the heel of the shoe for keeping heel protrusions off the ground.
- 2. Background Information
- In many athletic activities, participants wear special shoes that have spikes, cleats, taps or other protrusions extending outward from the bottom of the shoe. Examples of such activities include track and field, soccer, American football, baseball, golf, tap dancing and many other sports.
- Generally, the protrusions (especially, spikes, cleats and taps) are made from a metal, but they can also be made of hard plastic or rubber, or of other materials. Regardless of the composition of the protrusions, several problems are presented by such shoes. One problem is that the protrusions wear down quickly when a person wearing the shoes walks on a hard surface such as asphalt, concrete, dirt, metal or wood. Oftentimes, athletes will walk on the sides of their feet, on their heels or even in bare feet in an effort prevent the spikes, cleats or taps from contacting the hard surface and suffering wear and tear.
- Another problem, and one that is sometimes exacerbated by the first problem, is that it can be difficult to walk safely on hard surfaces when one is wearing shoes having spikes or other protrusions. The protrusions can cause the wearer to slip or they can catch on a surface and trip the wearer. Still another problem is that a floor or other walking surface can be damaged by the protrusions.
- In view of these problems, there are many examples of protective shoe coverings in the prior art that attempt to reduce these problems in various ways. One approach is to provide a protective sole that covers the protrusions extending from the athletic shoe. For example, U.S. Pat. No. 5,722,189 discloses a hard sole that covers the cleats on golf shoes. A problem with this type of athletic shoe covering is that a custom designed sole is required for each style of shoe, size of shoe or cleat pattern on the shoe. Another approach is to provide a slip-on cover that slides over part or all of the athletic shoe. For example, U.S. Published Patent Application No. 2004/0035026 discloses a pocket-like covering for spiked track shoes that slips over the front of the shoe. Coverings of this type are hard to put on because they can catch on the spikes or other protrusions.
- What is needed is a protective covering for athletic shoes that reduces the problems associated with shoes having protrusions from the sole and that will fit many styles and sizes of athletic shoes while being quick and easy to put on.
- Briefly, the present invention is a covering for shoes having spikes, cleats, taps or other protrusions extending from the soles of the shoes. The covering comprises a toe member and a heel member. The toe member is adapted for wrapping around the front part of the shoe having a sole from which one or more of the protrusions extend, and comprises a right flap, a right strap, a left flap, a left strap and a first bottom member. The right flap comprises a piece of material that wraps around at least a part of the right front side of the shoe and the right strap comprising an elongated piece of material that extends from the right flap. Similarly, the left flap comprises a piece of material that wraps around at least a part of the left front side of the shoe and the left strap comprises an elongated piece of material that extends from the left flap. The right flap and the left flap attach to each other with a first fastener to secure the toe member around the shoe. The first bottom member covers at least a part of the sole and prevents at least some of the protrusions from contacting a walking surface when the toe member is wrapped around the shoe.
- The heel member is adapted for positioning around the back part of the shoe and comprises a cup portion and a second bottom member. The cup portion comprises a piece of material that fits around the back part of the shoe and the second bottom member covers at least a part of the sole and can prevent some protrusions from contacting the ground. A second fastener is used to attach the right strap of the toe member to the heel member and a third fastener is used to attach the left strap of the toe member to the heel member to help in securing the heel member to the shoe. The heel member is a separate piece from the toe member when the right and left straps are not attached to the heel member.

FIG. 2 illustrates the protective covering positioned around theshoe 10. In the preferred embodiment, thetoe member 14 is wrapped completely around the front part of theshoe 10, forward of theopening 57 in theshoe 10 where the ankle of a person wearing theshoe 10 would extend out of the shoe. Theleft flap 28 is wrapped snuggly over the top of theshoe 10 with theright flap 26 wrapped over the top of theleft flap 28 and securely fastened to theleft flap 28 by thefasteners toe member 14, adjacent to thebottom member 32. A pair ofcuts 61 are made in theleft flap 28. - The
heel member 18 is positioned snuggly around theback section 23 of theshoe 10, behind theopening 57. Theleft strap 30 is attached to thecup portion 46 by thefasteners right strap 26 is attached to thecup portion 46 by thefasteners FIG. 2 . Theankle strap 54 is shown in an unattached orientation, but in use, it would be pulled over the ankle of a person wearing theshoe 10 and attached to thecup portion 46 using thefasteners - In alternative embodiments, the
ankle strap 54 can be eliminated and theheel member 18 is held in place using only thestraps heel member 18 around theshoe 10. A rear protective sole 62 is attached to the outside of theheel member 18, adjacent to thebottom member 48. On theleft strap 30, astitch pattern 63 is visible on the outside of thestrap 30 showing the stitches that hold the patch ofloop fasteners 42 in place. Also,FIG. 2 illustrates that thetoe member 14 and theheel member 18 do not cover one hundred percent of the sole 21 (shown inFIG. 1 ) of theshoe 10, because there is a gap between the front protective sole 60 and the rear protective sole 62 when themembers shoe 10. -
FIG. 3 illustrates theheel member 18 in more detail. In the preferred embodiment thecup portion 46 comprises a single piece of material having a cup shape that fits around the heel of theshoe 10. Two sections of thecup portion 46, aright section 66 and a left section 68 extend underneath theback bottom member 48 and meet at anintersection 70. Theintersection 70 is a cut in the material that extends back approximately to acurve 72 in thecup portion 46. An additional series of cuts (not shown) are made in theright section 66 and the left section 68 in a radial pattern. The cuts (approximately six to eight cuts) are approximately one inch in length and extend from thecurve 72 inward towards theintersection 70 in a semicircle pattern. The cuts help the material to be shaped into the cup-shape of thecup portion 46 by removing small amounts of material from between the cuts. - In the preferred embodiment, the
cup portion 46 comprises a strong flexible material that can be stretched without losing its original shape, such as neoprene. Preferably, thecup portion 46 comprises approximately three millimeter thick neoprene and theback bottom member 48 comprises approximately seven millimeter thick neoprene. The neoprene has a nylon covering on both sides. After the radial cuts are made (during die cutting) in theright section 66 and the left section 68, an adhesive that will form neoprene to neoprene bonds, such as a contact cement like Weldwood™ brand contact cement, is applied to the radial cuts so that the neoprene that was separated by the cuts is rejoined, and the material is folded into the cup shape. Similarly, the adhesive is used to join theright section 66 and the left section 68 along theintersection 70. - In the preferred embodiment, the rear protective sole 62 comprises approximately two to three millimeter thick thermoplastic rubber, such as Dynaflex® brand thermoplastic rubber. The rear protective sole 62 is attached to the outside of the
cup portion 46 using an adhesive, such as Loctite® 401 brand ethyl cyanoacrylate adhesive. A primer, such as Loctite® 770 brand primer is applied to the protective sole 62 first to facilitate formation of the thermoplastic rubber to nylon bond, and is allowed to dry. Then the adhesive is applied on top of the dried primer and the rear protective sole 62 is immediately pressed against the bottom of theright section 66 and the left section 68, thereby attaching the rear protective sole 62 to theheel member 18. - The
back bottom member 48 is attached to thecup portion 62 above theright section 66 and the left section 68, using an adhesive that forms nylon to nylon bonds (because the neoprene is covered with nylon), such as 3M Scotch-Grip Plastic Adhesive 1099™. The specific thickness and composition of the back bottom member depends on the type and size of theprotrusions 20. - Earlier in the assembly process, usually after die cutting the cuts in the neoprene but before shaping the
cup portion 62, the patch of thehook fasteners 50 is sewn onto the outside of thecup portion 62, so as to cover approximately all of the outside surface area of thecup portion 62, except for thestrap 54, theright section 66 and the left section 68. The patch of theloop fasteners 56 are sewn onto an inside surface of theankle strap 54. -
FIG. 4 illustrates thetoe member 14 in more detail. In the preferred embodiment theright flap 24 and theright strap 26 comprise a single piece of material. Similarly, theleft flap 28 and theleft strap 30 comprise a single piece of material. During manufacturing, theflaps shoe 10. A V-shapedspace 74 exists betweenright flap 24 and theleft flap 28. Aright portion 76 of theflap 24 is positioned underneath thefront bottom member 32, and aleft portion 78 of theflap 28 is positioned underneath thefront bottom member 32. Theright portion 76 and theleft portion 78 meet at anintersection 80. - The
intersection 80 is the interface where theright portion 76 and theleft portion 78 are joined. Theintersection 80 extends all the way up to thespace 74 so that theright portion 76 is separated from theleft portion 78 all the way up to thespace 74. Additional cuts are made in theright portion 76 and in theleft portion 78 to facilitate shaping thetoe member 14 into a shape that conforms to theshoe 10, by removing small amounts of material from between the cuts. Preferably, approximately five cuts are made in theleft portion 78 at forty-five to ninety degree angles to theintersection 80, and similar cuts are made in theright portion 76. The cuts can extend into theleft flap 28 as is indicated by thecuts 61 shown inFIG. 2 to help theleft flap 28 curve around theshoe 10. - In the preferred embodiment, the
right flap 24, theleft flap 28 and thestraps front bottom member 32 comprises approximately seven millimeter thick neoprene, and all of the neoprene used in thetoe member 14 has a fabric, such as nylon, covering both the inside and outside surfaces of the neoprene. After the cuts are made in theright portion 76 and theleft portion 78, an adhesive that will form neoprene to neoprene bonds, such as a contact cement like Weldwood™ brand contact cement, is applied to the cuts so that the neoprene that was separated by the cuts is rejoined. Similarly, the adhesive is used to join theright portion 76 and theleft portion 78 along theintersection 80. - In the preferred embodiment, the front protective sole 60 comprises approximately two to three millimeter thick thermoplastic rubber, such as Dynaflex® brand thermoplastic rubber. The front protective sole 60 is attached to the outside of the
toe member 14 using an adhesive such as Loctite® 401 brand ethyl cyanoacrylate adhesive, and a primer, such as Loctite® 770 brand primer, as was described previously with respect to the rear protective sole 62. After the adhesive have been applied to the front protective sole 60, it is quickly pressed against theright portion 76 and theleft portion 78 simultaneously, thereby attaching the front protective sole 60 to thetoe member 14. - The
front bottom member 32 is attached above theright portion 76 and theleft portion 78, using an adhesive such as 3M Scotch-Grip Plastic Adhesive 1099™. The specific thickness and composition of thefront bottom member 32 depends on the type and size of theprotrusions 20. - Earlier in the assembly process, usually after the cuts are made in the neoprene to shape the
toe member 14, the patch ofhook fasteners 36 is sewn onto the inside of theright flap 24, and the patch of theloop fasteners 38 is sewn onto the outside of theleft flap 28. InFIG. 4 , astitch pattern 82 is visible on the inside surface of theleft flap 28 showing the outline of the patch of theloop fasteners 38. Similarly, patches of theloop fasteners straps - Referring to
FIG. 1 , it is obvious that there are several ways that the protective covering can be assembled around theshoe 10. However, a representative way of putting on the covering is the following: The right and leftflaps toe member 14 are opened up as is shown inFIG. 4 . Then, while theshoe 10 is being worn, the toe (front part) of theshoe 10 is inserted into thetoe member 14 with thespikes 20 being positioned over thebottom member 32 and the toe of theshoe 10 being positioned between theright flap 24 and theleft flap 28. Theleft flap 28 is then folded over theshoe 10, theright flap 24 is folded over theleft flap 28 and the twoflaps hook fasteners 36 into theloop fasteners 38. - The
heel member 18 is then positioned around the heel (back part) of theshoe 10 with the sole of theshoe 10 resting on thebottom member 48. Theright strap 26 is pulled back towards theheel member 18 and theloop fasteners 40 are attached to thehook fasteners 50 on the right side of thecup portion 46. Then theleft strap 30 is pulled back towards theheel member 18 and theloop fasteners 42 are attached to thehook fasteners 50 on the left side of thecup portion 46. Finally, theankle strap 54 is pulled over the front of the ankle and theloop fasteners 56 are attached to thehook fasteners 50. Again, the order of attachment is not important and the shoe covering can be assembled in other sequences. Oftentimes, once the protective covering has been positioned over theshoe 10, it can be pulled off of theshoe 10 without unfastening thestraps shoe 10 at a later time, without unfastening thestraps - In alternative embodiments, the
straps toe member 14 that is positioned around theshoe 10 in a slightly different manner. In a first alternative embodiment, thestraps heel section 23 of theshoe 10, and theloop fasteners strap 30 to be attached to thestrap 26. For example, the patch ofloop fasteners 40 is replaced with a patch of hook fasteners, and the patch ofloop fasteners 42 are moved to the other side of thestrap 30 so that the loop fasteners occupy the region outlined by thestitch pattern 63 shown inFIG. 2 . After thetoe member 14 has been positioned around thetoe section 22 of theshoe 10, thestraps heel section 23 and hooked together using the hook and loop fasteners on thestraps heel member 18, and can be used in situations where theprotrusions 20 only extend from the front part of theshoe 10. However, even in this situation, it is preferable to still use theheel member 18, so that the front and back of theshoe 10 are both approximately an equal distance off the ground. - In a second alternative embodiment, the
straps straps heel section 23 of theshoe 10 after thetoe member 14 is positioned, thereby eliminating the need for theheel member 18. - There are many advantages inherent in the design of the protective shoe covering of the present invention. First, the flexibility of the neoprene used in the construction of the
toe member 14 means that a single size design of thetoe member 14 can fit many styles and sizes of theshoe 10. For example, it has been found that just three sizes of thetoe member 14 and three sizes of theheel member 18 can be used to fit all of the American shoe sizes from size three to size twelve or thirteen. This is possible, in part, because thetoe member 14 and theheel member 18 are comprised of a flexible material. Hence, as used herein, the term flexible material means a material that stretches to fit more than one shoe size. - Similarly, the ability of the
right flap 24 and theleft flap 28 to be pulled apart and opened up as shown inFIG. 4 , allows one size of thetoe member 14 to be used with several sizes and styles of shoe and makes it easy to position thetoe member 14 around theshoe 10. This is especially important when theshoe 10 has sole protrusions, such as cleats or spikes. If thetoe member 14 didn't open up, the protrusions would catch on the covering as it was pulled over the shoe. This also allows a person to step into thetoe member 14 without having to stand on one leg while they attempt to pull a covering over the shoe. - The fact that the
heel member 18 is a separate piece from thetoe member 14 also allows a single size of heel member to be used with several sizes and styles of theshoe 10. It is also easy to position theheel member 18 over theshoe 10 and use thestraps heel members shoe 10. - The use of both the
toe member 14 and theheel member 18 also makes it easier for the person wearing the protective covering to walk. If for example, a protective covering only covers the toe of theshoe 10, then a person wearing theshoe 10 is walking on an uneven sole. However, if both thetoe member 14 and theheel member 18 are used together, then a more even sole is achieved. The use of the front protective sole 60 on thetoe member 14 and the rear protective sole 62 on theheel member 18 facilitates the comfort and traction of the shoe covering. - There are many reasons for using the protective covering. First, for shoes that have the
protrusions 20, such as spikes, cleats, taps, extending from the bottom of the shoe, the protective covering protects theprotrusions 20 from wearing out prematurely. In this usage, the protective coverings are positioned around theshoes 10 when the wearer is off the track or playing field and is walking on a hard walking surface, like asphalt, concrete, wood or tile. Generally, it is thefront bottom member 32, and sometimes theback bottom member 48, that protect theprotrusions 20 from premature wear. The thickness and composition of the front and backbottom members protrusions 20. - For example, for track and field shoes, regulating bodies usually allow a maximum of six spikes per shoe, and these cannot exceed a quarter inch in length when running on all-weather track. Furthermore, all shoes worn by sprinters only have spikes in the toe region, not in the heel region. For such shoes, a seven millimeter thick neoprene
front bottom member 32 provides the primary protective cushion for the spikes to sink into, and is said to help prevent at least some of theprotrusions 20 from contacting the walking surface. The front protective sole 60 provides a durable sole that reduces the likelihood of slipping and also provides some extra cushioning for the spikes. If there are spikes on the heel of theshoe 10, then theback bottom member 48 will provide cushioning for these spikes, and is said to help prevent at least some of theprotrusions 20 from contacting the walking surface. However, even in cases where there are no heel spikes, theback bottom member 48 and the rear protective sole 62 are preferably used so that the heel and toe of theshoe 10 are resting on surfaces approximately the same height off the ground. For other types ofprotrusions 20, such as football or baseball cleats, or golf spikes, the composition and thickness of thebottom members - Another reason for using the protective covering is to cover dirty shoes, such as muddy soccer shoes. Use of the protective covering keeps the mud mostly inside of the protective covering, thereby protecting floors, carpets, car interiors or other areas from getting soiled. Similarly, it is often desirable to protect walking surfaces, such as floors, carpets, golf greens and other surfaces from damage by the spikes. Use of the protective coverings protects such surfaces.
- Although the present invention has been described in terms of the presently preferred embodiments, it is to be understood that such disclosure is not to be interpreted as limiting. Various alterations and modifications will no doubt become apparent to those skilled in the art after having read the above disclosure. Accordingly, it is intended that the appended claims be interpreted as covering all alterations and modifications as fall within the true scope of the invention.
