    • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • Before the present invention is described in greater detail, it should be noted that like elements are denoted by the same reference numerals throughout the disclosure.
  • Referring to FIGS. 3 and 4, the preferred embodiment of a shoe 100 according to the present invention is shown to include a sole unit 10 and a shell 20 secured to the sole unit 10.
  • The shell 20 has a front part 110 corresponding to a toe part of the shoe 100, a rear part 120 opposite to the front part 110 and corresponding to a heel part of the shoe 100, and two opposite intermediate parts 130, 140 extending between the front and rear parts 110, 120. The shell 20 further has opposite upper and lower surfaces 21, 22, a cutout part 23 formed in the front part 110 thereof and extending from the lower surface 22 to the upper surface 21, a bounding edge confining the cutout part 23, and a flexible corrugated portion 30 which has a peripheral end connected to the bounding edge. In this embodiment, the bounding edge includes a front edge 232 extending forwardly of the corrugated portion 30, and a rear edge 233 extending rearwardly of the corrugated portion 30.
  • The corrugated portion 30 is made of a material selected from the group consisting of a thermoplastic (plastic or rubber) material, natural leather, synthetic leather, and a fabric material, and has a peripheral end connected to the bounding edge of the shell 20. In this embodiment, the corrugated portion 30 has first and second peripheral edges 31, 32 connected respectively to the front and rear edges 232, 233 of the bounding edge by conventional techniques, such as sewing, adhesive bonding, and heat bonding. The corrugated portion 30 includes a plurality of crests 331 and valleys 332 that extend along a direction transverse to a line parallel to a front-to-rear direction of the shell 20, and a plurality of vent holes 34 formed in the corrugated portion 30. The corrugated portion 30 may be a molded body formed by a molding process. Alternatively, the corrugated portion 30 may be composed of a plurality of separate pieces. In this embodiment, the corrugated portion 30 extends across the shell 20 from the intermediate part 130 to the intermediate part 140, and is provided in the front part 110 of the shell 20 corresponding in position to an instep of the wearer. The vent holes 34 are through holes which may be formed in the corrugated portion 30 at any suitable positions to permit communication between the interior of the shoe 100 and the ambient air.
  • By virtue of the aforesaid construction, when the front part 110 is flexed and moved relative to the rear part 120 during walking of the wearer, the corrugated portion 30 will be extended and compressed along the front-to-rear direction so that the front and rear edges 232, 233 of the bounding edge move toward and away from each other (see FIGS. 4 to 6). When the corrugated portion 30 is compressed (see FIGS. 5 and 6), the air within the shoe 100 will be forced out through the vent holes 34 to the outside, as indicated by the arrows in FIG. 6. When the corrugated portion 30 is thereafter extended, the ambient air is drawn into the shoe 100 through the vent holes 34. In other words, the present invention utilizes the flexing and unflexing actions of the shell 20 at the corrugated portion 30 during walking of the wearer to achieve exchange of air between the air inside the shoe 100 and the ambient air to thereby expel the heat, moisture, and bad odor pent-up within the shoe 100.
  • In addition to having the capability to ventilate the shoe 10, the corrugated portion 30 also facilitates flexing of the shell 20. Moreover, due to the arrangement of the corrugated portion 30 in the front part 110 of the shell 20 where the shell 20 will be bent when the user flexes his/her foot during walking, generation of undesirable creases at the front part 110 of the shell 20 can be avoided.
  • It is worth noting that a waterproof breathable film (not shown) can be applied to an inner surface of the corrugated portion 30 to provide waterproofing and ventilating functions when the shoe 100 is adapted for use as a waterproof shoe.
  • Referring to FIGS. 7 to 9, the corrugated portion 30′ of the shell 20 of the second preferred embodiment of a shoe according to this invention is shown to be substantially similar to that of the first preferred embodiment in construction. The major difference therebetween resides in that, in addition to the vent holes 34′, additional vent holes 341′ are formed at the peripheral end of the corrugated portion 30′ by sewing the first and second edges 31′, 32′ of the corrugated portion 30′ to the front and rear edges 232, 233 in such a manner as to form the vent holes 341′ between the front edge 232 and the first edge 31′ and between the rear edge 233 and the second edge 32′. With the provision of the vent holes 341′, ventilation of the shoe according to this invention can be further enhanced.
  • Certainly, the corrugated portion 30′ can be formed from a plurality of separate pieces connected together by sewing, and the vent holes 34′ are holes through which the sewing threads pass (not shown).
  • FIG. 10 shows the third preferred embodiment of a shoe 100′ according to this invention. As shown, the shoe 100′ is in the form of a boot having a shell 200 which is composed of a lower 200A and an upper 200B. A corrugated portion 300 is provided in a front part 110′ of the lower 200A corresponding in position to the instep of the wearer so as to permit circulation of air through the corrugated portion 300 when the wearer walks or squats.
  • Referring to FIG. 11, the fourth preferred embodiment of a shoe 100′ according to this invention is also in the form of a boot, and differs from the third preferred embodiment mainly in that the corrugated portion 300′ is provided in the rear part 120′ of the shell 200 at a location above the heel of the wearer. As such, when the wearer walks or squats, the shoe 100′ can be ventilated.
  • Referring to FIG. 12, the fifth preferred embodiment of a shoe 100″ according to this invention is also in the form of a boot, and differs from the previous preferred embodiments mainly in that the shell 200′ further includes a tongue 150, and that the corrugated portion 300″ is provided in the tongue 150. Referring to FIG. 13, the tongue 150 may include a soft and porous filler 151 disposed between the corrugated portion 300′ and a lining 152 to provide comfort as well as ventilation.
  • In summary, with the arrangement of the corrugated portion at the front part or the rear part of the shell, the shoe of this invention can virtually breathe, and can bend or flex easily without creating unsightly creases on the shell.
  • While the present invention has been described in connection with what is considered the most practical and preferred embodiments, it is understood that this invention is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
