Abstract

SHOE WITH SUPPORTED HEEL
ABSTRACT OF THE DISCLOSURE
The invention comprises a sport shoe to be used by runners. In order to obtain increased rear foot stability the shoe comprises an outside counter and a pair of straps extending upwardly and forwardly from the counter, one strap on each side of the shoe. The end of the straps comprises a lace receiving aperture. The apertures of the normal eye stay and the apertures in each of the straps are substantially aligned in order that the lace used in association with the eye stay may also be passed conveniently through the aperture of each strap.

Description

This invention relates to sports shoes, in ; particular a running shoe having improved structure to support the heel of the runner.
Runners who are interested in running distances - 5 which might be classed as intermediate to longer distances have becorne aware of the desirability to run in a shoe which provides maximum shock absorbing capabilities which ; is at the same time quite light.
Heretofore,efforts have been made to design shoes which provide superior shock absorbing capabilities and which are significantly lighter. However, as the shoe is made lighter it becomes more difficult to provide appropriate stability in the shoe. Additionally, as more shock absorbing material is added to the sole of the shoe there is a greater flexibility in the shoe which further reduces stability.
- Studies have shown that during the running stride the normal foot will tend to roll inwardly as the weight is placed upon the foot. This is referred to as prona-tion of the foot. Excessive pronation of the foot is ob-jectionable and will lead to injuries to the foot, ankle and leg of the runner. By using a softer component for : ..... .

- the midsole and in the wedge area of the shoe for shock absorption the shoe can sink or rotate with respect to the sole as the runner's weight comes to bear on the sole of the shoe. For the sprinter, the weight of the runner is 5 placed almost entirely upon the forward portion of the shoe. However, in the case of the runner involved in intermediate to long distance running, rear foot control becomes of the utmost importance to reduce injury. Here-tofore, rear foot control for shoes intended for middle to ` 10 long distance runners has been provided by the counter of the shoe. The counter is that portion of the shoe which A surrounds the lower heel portion of the upper and usually comprises a layer of material which serves to reinforce the basic material of the shoe upper. The counter may be 15 either an internal or external counter. The term external counter is used to describe the form of counter in which the counter is visible from outside the shoe and comprises an additional piece of material stitched or otherwise affixed to the upper of the shoe.
According to this invention a shoe having improv-ed stability and rear foot control is provided. A shoe made according to the invention comprises an external counter surrounding the heel portion of the upper. Extend-' ing upwardly and forwardly from the counter are a pair of straps, one located on either side of the shoe. The straps are fixed to the counter and have an aperture for receiving a lace located adjacent the end of the strap which is re-mote from the counter~ The length of each strap is such that the aperture of the strap is sulstantially aligned .~ .

with the apertures of the usual eye stay.
The invention will be better understood ln assoc-iation with the following drawings which illustrate pre-~ ferred embodiments of shoes made according to the invention ; 5 and in which like numerals are used throughout the draw-ings to identify like parts and in which:
Figure 1 illustrates a shoe made according to the invention, and Figure 2 illustrates a second embodiment in which the straps are attached to the eye stay of the shoe by a gore.
The shoe 20 comprises a sole 22 and an upper 24.
In the heel portion of the upper 24, there is located an external counter 26 which serves to give additional stabil-ity and bracing to the rear foot area of the shoe. Theupper of the shoe additionally comprises a conventional eye stay 28 adapted to receive a lace to firmly tighten the shoe to the wearer's foot. The upper of the shoe also comprises a pair of straps 30 and 32 which extend upwardly and forwardly from the counter 26 to the eyè stay 28. Lo-cated inwardly from the eye stay and adapted to bear again-st the instep of the runner's foot is a conventional tongue 34.
Eye stay 28 comprises a plurality of apertures 36 ~5 and 37 adapted to receive a lace 38. The apertures 36 and 37 are in substantially aligned rows extending along the eye stay on either side of the mid line of the shoe in conventional fashion. Strap 30 also comprises an aperture !' 40 located adjacent the end 31 thereof.

, Strap 32 comprises a similar aperture 42 located adja-cent the end 33 thereof. It will be observed that the lace 38 may be threaded in conventional fashion through each of the apertures 35 and 37 of the eye stay 28 and through the apertures 40 and 42 in straps 30 and 32 respectively. Each r~' of the straps 30 and 32 is long enough to extend from the counter 26 such that the apertures 40 and 42, respectively, are located substantially aligned with the corresponding apertures of the eye stay. By locating the apertures 40 and 42 in this manner, the single lace 38 may be conveni-ently threaded through all of the apertures. Thus, when the shoe is laced up the two straps 30 and 32 are adjacent the uppermost portion of the eye stay but independant therefrom.
It will be observed that the topline 4~ of the shoe extends about the uppermost and rearmost portion of -- the upper to define the portion of the shoe which bears against the ankle of the wearer. The forwardly portion of - the collar is comprised by the upper edge 46 of the strap 30 and the upper edge 48 of strap 32.
In order to use the shoe the lace is loosened sufficiently to allow insertion of the runner's foot in the conventional manner. The lace is then tightened by pulling each of the various reaches of the lace in the eye stay in a direction which is upwardly and toward the shin of the wearer against the apertures 36 and 37 all in conventional fashion. Sufficient apertures 36 and 37 are provided to securely fit the eye stay and vamp portion of the upper to th~ instep of the runner. The final pass of the lace is ,;
.

through the apertures 40 and 42 and by virtue of their loc-ation adjacent the eye stay, the lace passes through each of the apertures in the same fashion as through the aper-;~ tures 36 and 37. The final step before tying the lace how-ever, is achieved by an upwardly and outwardly pull on the ` lace 38. The direction of this pull is in a direction par-allel to the length of the strap awa~ from the counter.
That is, the lace is tightened by pulling outwardly and upwardly with reference to the heel. It is suggested that lO a 45" angle pull will be the best. The lace may then be tied in a conventional bow located at the space between the straps 30 and 32 as though the straps were a conventional - upper edge of the eye stay. By pulling upwardly and out-wardly as described on the straps 30 and 32, the straps and 15 lace are used to further increase the stability and bracing of the counter 26.
In order to fully appreciate the function of the straps 30 and 32, reference should be had to the lines of stitching as shown in the figures. The function of the two 20 straps is identical and the stitching on strap 30 will be discussed in detail.
The strap 30 is first firmly affixed to the co~m-ter along the lines of stitching identified by the numeral 50. The lines of stitches 50 will be the conventional line 25 of stitching affixing the counter to the upper of the shoe in the heel portion. These stitches in the shoe of this invention are also used to attach the strap 30 directly to the counter and the upper. Stitches 52 affix the strap 30 to the upper. It will be observed that the stitches 52 ex-, ;~ 6 i tend only to approximately the midportion 54 of the strap 30. The stitches 56 are used to affix the strap to the upper rear portion of the quarter of the shoe to constitute the t~pline ~4. It will be observed that the strap 30 is separated from the e~e stay so as to be independent there-from in the direction along the instep of the shoe.
A conventional shoe having an eye stay cannot pull forwardly on the heel of the shoe as the eye stay is attached firmly to the vamp or top portion of the upper.
Thus, any attempt to pull upwardly and outwardly as des-cribed above, with a conventional shoe only results in loosening the fit of the shoe. A force in this direction exerted on the eye sta~ is anchored by the toe and instep of the shoe rather than the heel. The purpose of the strap 30 15 which is not affixed to the eye stay in the direction along the instep of the foot is to ensure that the force placed on the strap by the upward and outward pull on the lace is resisted only by the heel portion of the shoe. This pull on the strap is resisted by the stitches 52, the stitching 50 and counter 26. Thus the stitches 52 and 50 together with the counter 26 present the anchor against which the pull on the strap reacts. ~hen tied, the counter, heel and ; collar are all braced by the reaction against the instep of the foot. This reaction tends to substantially stiffen the ~5 heel portion of the shoe and provides increased stability to resist over pronation of the foot. In the conventional shoe regardless of how tightly the lace is pulled no force is directed-backward towards the heel with all forces rath-er being directed toward either the ball of the foot or at `' `` 7 most the arch support of the foot. It will be observed that the shoe comprises an unusual lower tooline a5 which separates the forwardly portion of the vamp of the upper from the strap 30. The lower topline 45 meets the strap in 5 the vicinlty of the midpoint of the strap 54.
Figure 2 illustrates a shoe which is similar to the shoe shown in Figure 1 with the exception that the straps 30 and 32 are joined to the eye stay by means of an elastic gore 60 and 62 respectively. The purpose of the 10 gores 60 and 62 respectively is to ensure that the straps do not hang freely of the shoe as shown with the embodiment illustrated in Figure 1. It is conceivable that the straps which have free ends 31 and 33 in Figure 1 may become sub-ject to tearing. If so, the embodiment with the gore 15 should substantially reduce any chances of the straps tear-ing. If there is to be any tearing of the straps it will occur by tearing across the mid portion of the strap 54.
The gore 60 will limit movement of the straps in the direc-tion parallel to the instep 60 as to eliminate any chances 20 of tearing but does not otherwise affect the independent r action of the strap. The strap thus transmits forces to the counter independantly of the eye stay. The gore is an expandable elastic material which is well familiar to those skilled in this art. The gore may be of the same material " 25 as is conventionally used in the instep area of moccasin type shoes wherein no form of lacing is embodied. In all other respects the embodiment shown in Figure 2 is the same .. ~' ' .

d ~ .

o as that shown in Figure 1.
In Figure 2 the lacing has been deleted from the figure and the tonaue 34 has been depressed down into the shoe so that the inner portion of the eye stay and the strap 32 is visible.
As the shoe manufactured in accordance with this invention is independent of the specific construction of the sole 22, a simplified form of sole has been illustrated. It will be obvious to those skilled in the art that the shoe of this invention may comprise any form of suitable sole comprising a suitable lower traction surface, various forms of midsole involving wedges or other cushioning construction together with a suitable upper sole to which the shoe upper may be attached. It will also be appreciated by those skilled in the art that the counter 26 illustrated in the drawings is a particular simple form of counter which extends about the heel of the shoe to provide stiffness in this area.
If desired the counter may extend up to the topline 44 in the vicinity of the ~chilles tendon. It will also be ~ appreciated by those skilled in the art that the toe - of the shoe may contain additional reinforcing or strengthening fabrics. As the exact construction of the frontal portion of the upper plays no part of this Z5 invention such optional features have not been included.
In the shoe as illustrated in each of Figures 1 and 2 the eye stay is shown to comprise a plurallty of apercures extendin~ through the eye stay and the lower . , ,, ~ , ~2~

.: g .
vamp portion of the shoe. Those skilled in this art will appreciate that the exact configuration of the eye lets of the eye stay can be altered so long as the laces perform the function of tightening the shoe over the wearer's instep. In many cases familiar to those skilled in this art shoes are now manufactured with a form of speed lace eye which comprises a loop of plastic or like material affi~ed to the inner edge of the eye stay. These so-called speed lace eyes then form the - 10 function of the apertures shown in the drawings.
While the preferred embodiment illustrated in the drawings are intended for use with runners of middle to longer distances~ it will be obvious to those skilled in the field that the shoe construction may be used with any type of shoe wherein it is desirable to have an increased stability of the rear foot. Thus, while the shoe has been shown with reference to a running shoe the construction may also be used with shoes intended for use in sprint running or indeed for use in any other support where it is desirable to prevent over pronation of the wearer's foot.
Those skilled in the art will appreciate that many modifications may be made to the shoe without depart-ing from the scope of the invention as described in the appended claims.
