' This invention relates to footwear and, more particuthe uppers are normally fabricated does not provide suf-.

ficient supportfor the ankle. Additionally, footwear heretofore available has generally proven unsatisfactoi'y in thatchafing and irritation occur at the sides of the ankleand lower back of the heel, which are inherently tender areas. A

' Accordingly, it is the primary object of this invention to provide a novel and improved article of footwear having an integral ankle and heel support member which will provide improved support for the heel and ankle of the wearer while at the same time protect the tender heel and ankle portions from chafing and irritation.

It is a further object of the present'invention to provide such an article of footwear in which the footwear may be readily put on and removed from the foot by means of lacings or other closure means, with the same closure means also'serving to firmly engage the ankle support member about the foot of a wearer and ajust the tension necessary for proper support and comfort.

It is still another object of this invention to provide an article of footwear of the type described which will provide added comfort for the wearer as well as the improved ankle and heel support while at the same time will not detract from the pleasing appearance of the footwear.

. The manner in which the objects of this. invention are accomplished will be apparent from the following detailed description of a specific embodiment of the invention-when taken in connection with the accompanying drawings, in which: I

Fig; lis a fragmentary elevational view, partly in section, of an article of footwear constructed in accordance with the present invention;

. Fig. 2 is a plan view of an ankle support member of thepresent invention prior to assembly withina shoe; Fig. 3 is a cross sectional view substantially along the line 33 of Fig. 1;

4 Fig. v4 is an enlarged fragmentary cross sectional view substantially along the line 4-4 of Fig. 1; and

Fig. 5 is a fragmentary cross sectional view similar to Fig. 4 illustrating a modified structure.

The following description of a preferred embodiment of the invention will be made in terms of the specific structure shown in the accompanying drawings, which is a shoe of the type often referred to as a basketball shoe. However, it is to be understood that the invention is not limited to this particular type of footwear but Pat t J n 8.19 0

is applicable to other articles of footwear in which ankl support is necessary or desirable.

With reference'to Figs. 1 and 3 of the drawings, an exemplary article of footwear with whichthis invention is concerned comprises an upper generally shown at 10 comprising a plurality of layers of material. Theupper includes ashank 12 and aback 14, and as shown in Figs. 1 and 3, the upper extends upwardly beyond and is constructed to be drawn about the ankle and over the instep of a wearer. As isrusual, fastening means are provided to secure the shoe to the ,foot of a wearer and comprise, as elements thereof, a pair of sets ofeyelets 16 which are generally aligned along eachfront edge 17 of the upper. The eyelets will, of'course, receive laces, not shown, which cooperate with the eyelets in theusual manner to provide means for drawing the upper in a direction over the instep and around the ankle of the wearer. As shown in Fig. 4, the eyelets extend through a pliableouter layer 18 of the upper and also through an eyelet stay 20 overlying theouter layer 18 and permanently stitched thereto. Aback stay 22 strengthens the back of the upper. .The upper is permanently connected along its 'loweredge portionsto a sole 24 comprising an outsole 2.6,midsole 28, andinsole 30. As will be seen from, Figs. 1 and 3, theouter layer 18 and backstay 22 are tucked under and between theoutsole 24 andmidsole 28. Theinsole 30, in the specific embodiment shown, is preferably fabricated of a resilient, sponge-like material to provide comfortable support forthe bottom of the foot of the wearer. h

-In accordance with the invention an ankle andheel support member 32 is disposed within the upper 10 and permanently stitchedthereto as at 34 to form an'integral part of the upper. As best shown in Figs. 2 and 3,thesupport member 32 comprises alayer 36 of resiliently deformable while substantially incompressible sponge-like material, such as uni-cellular or cellularpsponge rubber, a stiffening rubberized compound, a rubber impregnated fabric treated with hardening liquid, etc. Thelayer 36, having the characteristics described, will, when firmly engaged about the heel and ankle of a wearer, conform generally to the contours of the portions of the foot engaged thereby to provide firm support for the foot while at the same time eliminating any chafing or irritation of the tender heel and ankle portions of the foot. The support member further comprises abacking layer 38 which overlies and is cemented or otherwise permanently secured to thesupport member 32 and which may be fabricated from canvas or other like pliable material which is relatively unyieldable to stretching in the general plane of the layer. This latter feature is desirable I in order to minimize any stretching of the ankle support member which would tend to reduce the support of the portions of the foot engaged thereby.

With particular reference to Fig. 2, the support member and backing layer each comprises a'bottomedge 40, aback portion 42, a pair oftop edges 44, and a generally curved, angular or V-shapedfront edge 46 extending from'each ofthertop edges 44 to the bottom edge40. When located within the shoe, as will be apparent from 'Figs.1 and 2, the support.member 36 will assume a generally U-shaped configuration, with-the then generally U-shaped bottom edge 40-extending from within the shank region'12 on one side of the shoe rearwardly and around the heel seat and forwardly to a position on the other side of the shoe corresponding to theshank region 12. The then curved back portion 42' of the support member will. lie alongside and within theback stay 22, with the body of the support in position to embrace the ankle'and heel ofa wearer.' '-As apparent fromFigs. 1

and 3, it is preferred that the bottom edge portion of the support member be tapered and interleaved between the midsole and outsole. A reinforcingcounter 48 is provided around the heel portion, and the bottom edge of the counter is also preferably tapered and interleaved between the midsole and out-sole. Thecounter 48 preferably comprises a layer of resiliently deformable substantially incompressible material such as rubber but which is firmer than the material of thelayer 36 of the support member.

As clearly shown in Fig. l, the counter is permanently stitched to theouter layer 18 of the upper as well as the intervening layers therebetween. Additionally, as is clear from Fig. 1, thetop edge 44 of the support member is permancntly'stit'che'd to theouter layer 18 of the upperand extends upwardly of and above the ankle bone region of the shoe. Further, as shown in Fig. 1, the front;edges 46 of the support member, when the support member is positioned in the shoe, will lie adjacent the fastening elements oreyelets 16 and extend from above the ankle region of the shoe generally parallel to and closely adjacent theupper eyelets 16, by means of which the shoe is drawn about the ankle and over the instep of the wearer. The initial portion of thefront edges 46 terminate in the instep region of the shoe and from there the front edges incline rearwardly and downwardly through theshank region 12 to the sole of the shoe. As apparent from Fig. 1', thetop edges 44 andfront edges 46 of the support member are permanently stitched to the upperouter layer 18 and any intervening layers of material. As further apparent from Fig. 1, it is preferred thatfront edge portion 44 extending parallel to theeyelets 16 be superposed with theouter layer 18 and fastening means stay 20, as shown in Fig. 4, to assure that when the upper. is drawn about the ankle and over the instep of the wearer by the fastening means, the support member will be firmly engaged with the ankle and heel regions of the wearer to provide firm support for the same. The characteristics. of thebacking member 38, whereby it is substantially unyieldable to stretching in the general plane of the layer, further assures that the support member will be firmly engaged with the foot to provide improved support as well as antichafing protection. a

As will be apparent to those skilled in the art, it is not necessary that the backing member orlayer 38 be the specific means for providing the characteristic of the upperwhereby it is substantially unyieldable to stretch-. ing as the upper is drawn over the foot. Rather, this characteristic of the shoe may be provided by the proper selection of, one of the other layers of material forming the upper. Further, as will be apparent to those skilled manently connect the fastening means directly to the support member. In this maner, the tension provided by the fastening means will be transmitted directly to thesupport member 32 to further improve the supporting engagement of the support member with the foot of a wearer.

From the above it can be" seen that there has been provided a novel and improved article of footwear having an integral ankle and heel support member which will provide improved support for the ankle and heel of a wearer while at the same time 'will protect the tender regions. of the heel and ankle against chafing. The improved construction of the shoe of this invention while providing the improved, support and anti-chafing previ-. us y ment cne lso pro id a pleasing, n u y pp i an the pa t cular arr emen a d onst u ti n. f the support member relative; to. the upper permits easy 4 fitting and removal of the shoe to and from the foot of the wearer while at the same time eliminating any separate lacings or other fastening means for securing the support member about the foot of the wearer.

As heretofore mentioned, it is not intended that the invention should be limited to the specific structure shown but rather that it should include all articles of footwear in which the problem of ankle support and/or chafing is present. Accordingly, the invention is to be limited only by the appended claims, which shall include within their scope all structure which logically falls within the language of these claims.
