ARTICLE oF FOOTWEAR I Filekd March 16, 1950 Patented May 19, 1953 UNITED STATI-Es PATENT oFF-1ct; y y L y V2,638,601 l l ARTICLE oF FOOTWEAR Edward P. Bullard In, miniera, conn. .Application March I16, 1950, Serial No. 149,997
'I'his invention relates to `athletic footwear, particularly to that type used-in sports which require a relatively heavy boot being securely laced to the wearers foot. A ski-boot, for example, must *bev so tightly laced as to insure the users foot being held rigidly secured to the associated ski.
4This requisite tight lacing is sometimes extremely uncomfortable, so much so as to frequently require loosening at the end of a run,` which in turn necessitates re-tightenng before the next run. i
An object of this invention to .provide an improved -article of footwear constructed and arranged to permit an athletic shoe such, for example, as a ski boot, being secured to the wearers -foot vwith any degree of tightness required to -insure substantial rigidity between the foot and boot, and entirely without discomfort.
A further object is to provide an'improved sock constructed and Varranged to insure the necessary tightness of an ordinary ski boot or the like without requiringthe boot itself to be tightly laced. 7
A further object is to provide ya, positioning device arranged to insure and maintain the cor-'- rect positioning of the wearers foot in a shoe,
'of construction and arrangement shown, but may l embodyvarious changes and modii'lcations within the scope of the invention.
In the drawing: j f Fig. l is a vside elevation showingbne embodiment of the invention in use on a wearers foot; Figs. 2 and 3 are sections-on the lines 2-2 and 3-3 respectively, of Fig. l, and Fig. 4' is a partial elevation showing the opposite side of the foot from Fig. l.
,For the purposes of disclosure, the invention is shown employed with'a ski boot II having'the usual sole I2 and upper I3 provided with hooks I4 for usev in lacing the boot to a wearers fo'otI5.
6 claims. (01..',2-239) A characteristic of all ski boots is the rigid, non- A 'flexing nature of the sole and heel portion therepf. These boots are constructed in a mannervto prevent any viiexing between the sole and v"heel .and often employ a rigid metal plate extending from the.= heelvv to the sole forming-one lofgthe laminae of the sole and heel construction. The
presentr invention provides an inatable device -or bladder that .permits the relatively loose lacing of such boots to avoid Idiscomfort tothe wearer while providing an arrangement which,
'when inflated, insures the requisite high degree of rigiditybetween the foot and the boot required in various sports, such asskiing.
Referringto the drawing,:the inflatable device is shown as .applied to a sock I6 of textile material whichfforms the entire inner surface of the sock in contact with the wearers foot. In the embodimentdisclosed, the sock I6 is shown as provided with an iniiatable sectionfcovering an area on the-top of the wearers foot over the instep iand along the outer side of the foot from a point forward of the instep to a `point near the heel, and a second inatable section on the outside of the rfoot connected tothe rst section and extending along the back of the foot at the inner side of the heel. Y I
,As illustrated, an inflatable bladder I1 of uid tightsmaterial, such, for example, as rubber; has inner and outer-*walls I8 and I! respectively,
Vconnected at their edges 2I. lThe bladderv I'I lin -the embodiment disclosed forms an integralpart `of the sock. As illustrated, the inner Wall I8 can bev adhesively securedv to the outside face of the textile lmaterial I6, or the bladderc'an lbe incorporated in the sock to form apart of the wall thereof, in' any manner desired.` As shown in Fig.` l, the bladder II is so shaped as to cover the top of the wearers'foot underthe boot vent 22 and tongue 22a over the instep,` and also along the outer side Vof the foot from a point forward of the instep to a point adjacent the heel23. Thebladder IIis formed so as to leave an opening 24 over the outside ankle 24a of the 'wearer uncovered, andthe inside ankle 25 is also .left uncovered by the bladder'. The 'bladder I1 includes a section 26 located in back of the'o'utside ankle to fillthe space between this part of ,the foot-and the shoe or booty Il. The bladder Il is formed to extend across the topof the foot vpast the vent 22 farenoughtq provide a pressure 'absorbing cushion over the -arch of the foot so thatthe latter is cushioned against concentrated pressure produced by tight lacing. An additional bladder section' 28 on the inside of the foot isr so located as to fit the area at the rear of the inside lankle 425'above 'the heel. I
applying the mner wall'fIS of the bladder to the material of thesock in any suitable manner, adhesively or otherwise, the bladder forms 'an' integral part of the sock I6 which in no way -bootf is .1 removablef upon unlacing.-
3 affects the ease with which it can be put on or taken off by the wearer.
The bladder I1 is preferably formed to extend upwardly above the wearers ankle, and below the top of the ski boot or the like, and means is provided for inflating and deating the bladder after vthe boot is laced over it. As illustrated, this includes a spring pressed check valve 3l connected to l,the outer end of a .,tube,3-2 cornmunicating withI the inner space cfu-the. bladder l1, and extending upwardly to a point above the boot Il. A valve stem 33 is accessible from the outer end of the tube for opening the valve for" The valve 31Vcan have;

that used in valves for pneumatic tires; or theV like.
in the bladder as ,long vas desired.. Before-removingl the) boot the-valvefstem 33.;is ,pressedinz wardlvy..l to f, deflatei the bladder, after;l which .the In ,place of a separate. 'hand'I pump a 1 rubber; bu1b;;pum-p with suitab'lewalvingcan be;permanentlyconnected to fthesbladder vfor inflatingand deating, ,ifV desired..` l
