Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to athletic shoes. The recent increase in running-type exercise activities for maintaining physical health not only maintains the intended health-promoting effect, but also causes more injuries. It includes injuries to the ankle joint as well as injuries caused by repeated impact of the heel on a running surface.

The present invention provides a novel athletic shoe having a specialized sole assembly that incorporates a stabilizing tank board in the heel region between the outsole and the midsole that extends forward into the midfoot region. be. The midsole is made from a compressible polymeric material. The tuck board controls the torque between the tarsal and metatarsal regions and provides stability to the foot as the athlete's weight shifts. The upper surface of the underlying outsole has a polymeric shock-absorbing grid that projects upwardly and engages a tack board, which separates the grid from the midsole and thereby secures the grid during use. It also prevents the clid from disintegrating the relatively soft, compressible midsole due to movement to and from the midsole. Next, preferred embodiments of the present invention will be described with reference to the drawings.

For example, an athletic shoe assembly 1° useful for basketball or other running errand athletic activities is comprised of a sole subassembly 12 and a leather subassembly 14.

The sole subassembly is composed of a rubber shell surface 1116, a tank board 18, an intermediate Narita, a wedge n, and an inner sole. The specific nature and interrelationship of these components will be discussed below.

The leather subassembly 14 consists of a soft, close-fitting inner shoe subassembly portion and an outer shoe subassembly blade that includes an external heel counter 32, an external toe leather 34, and an external removable ankle strap. Within the inner sole, on each side of the shoe, are a pair of fixed tension strip bales, for example made of auxiliary nylon. The specific nature and interrelationship of these components will be discussed below.

The outsole 16 includes a peripheral shell that forms the outer sole layer of the shoe, with an outer traction grid 16', and surrounds the other sole components as well as the lower portion of the shoe midi in its peripheral upright wall 16a. The front peripheral portion of outsole 16 may be roughened as shown if desired. Seam 17 passes through the upright walls and the layers of shoe china around the periphery of the shoe. The overall thickness of the outsole is generally uniform except that in the heel area, the extra peripheral thickness allows for the formation of a cavity or pocket for receiving the tuck board. This tack board has a stiffness substantially greater than that of a rubber outsole and is formed from compressed cellulose board or a semi-rigid nonwoven material with limited bending ability, and has a heel section. It extends from side to side and forward to the midfoot region of the foot, i.e. under the instep of the shoe, over the entire heel area. In the top of the outsole pocket, i.e. just below the rear part of the tuck board,
A rubber grid 19 consisting of upright protrusions and an intermediate space is integrally formed (FIG. 7). The grid 19 tapers downwardly and forwardly from the rear of the tuck board 18 so that the thickness of the outsole 16 also tapers from the rear of the shoe to the grid 19.
The tack board 18 tapers downwardly to an area below the tack board 18, which extends through the tack board 18. This grid separates the midsole from the grid to create additional heel cushioning in the high impact area of the heel and to prevent the clid from disassembling the midsole by rubbing against the midsole during use of the shoe. . The relative friction of the smooth bottom surface of the tack board in engagement with this grid allows movement between these components without disassembling the tack board during use of the shoe. The grid is thus located at the top of the tankboard in the area of the grid, separated from the sole and virtually over the entire heel area. The intermediate sole extends across the width and length of the sole subassembly/pre.

Immediately above the midsole is a wedge that tapers forward, providing a shock cushioning effect in the heel area and gradually merging forward, where the wedge does not extend in line with the midsole. Transfers smoothly to the front part of the shoe. An inner base is located on the wedge and intermediate base. The intermediate base and wedge n are formed from an elastic cancellous material such as, for example, ethylene vinyl acetate (EVA) manufactured by E.I. du Pont'Nemours K. of Wilmington, P.O. The inner sole U is a thin layer of compressed material, such as compressed paperboard of the type commonly used for this purpose. If desired, an inner sole padding layer (as shown).

(not shown), which may be fixed in place or removable.

□The shoe china, particularly the subassembly wing, incorporates a foot-encircling, close-fitting material, such as soft-sided cowhide leather, and optionally has a fabric lining on at least a portion thereof. A padding layer 31 is arranged in the heel and ankle region, the inner surface of which is covered with a nylon fabric or the like, and the outer surface covered with a leather layer 29. Near the upper point of the shoe, padding of flexible foam of spongy polystyrene or the like is used, again surrounded on the outside by a layer of leather and on the inside by a layer of fabric.

Similarly, a spongy polyurethane foam 35' is incorporated into the tongue and is coated on the outside with leather or other suitable material 291 and with nylon 331 on the outside.

At the tip of the shoe, the shoe has a regular opening that can be closed with a regular lace.

extending upwardly and rearwardly within the shoe, preferably of nylon;
There is a pair of diagonally oriented tension strips 40, the lower ends of which are secured to the sole subassembly in the mid-section of the shoe above the front of the tack board 18 by seams 17, and which tension strips extend along their entire length. sewn into the side wall of the The top ends of the strips overlap and form an external heel counter 32.
is sewn on. These strips and the heel counter form a tension band means along the sides of the ankle and around the back of the Achilles' heel of the foot. These cooperate with the external tensioning straps 36 to provide cruciate, controlled tightness, reinforcing stability to the foot, particularly its ankle.

The heel counter 32 extends forward from the rear of the shoe to the ankle area on each side. This heel collar is made of rigid tanned leather.

There is a pair of elongated external tension straps integral with the outside of the shoe heel counter. These leather flexible straps can be used to tie down the ankle by extending over the laces on the front of the foot, ie over the anterior ligament area.

Specifically, the valley strap has a length sufficient to extend from one side of the heel counter across the front of the shoe to the other side and then back to where fastening occurs. As shown, each leather strap is integral with the external heel counter on the outside of the shoe, extends across the anterior ligament area and above the laces, and has a loop secured to the heel counter on the inside of the shoe. Alternatively, it can pass through a group of rectangular rings and then return to the outside of the shoe and be fastened in a completely removable manner. It is fastened to the underlying portion of the strap by cooperating hook-tube loop fastening means, such as a "Velcro" type hook-loop 7 assuna. The loop portion is secured to the outside surface and to the underside of the other overlapping or overlying strap portion. Each strap is tightened to a selected tension and held by seven attenuators.

material 51, thereby limiting the lateral expanse of the toe strap. This toe leather is sewn to the inner shoe subassembly. This toe leather is also secured to the outer peripheral wall of the outer lower sole by seams 17. A textile intermediate strip 37 is also sewn to the outer circumferential wall of the outer lower sole and extends between the toe strap and heel counter 32 on either side of the shoe.

The shoe of the invention described above combines a number of special features. Certain of these features can be used independently as well as in the combinations shown. Specifically,
Cross-shaped reinforcements using internal tension strips and external tension bands can be used independently or in combination with stability-adding, anti-abrasion tucks in the sole subassembly, and these provide a close-fitting internal shoe and an external Can be used individually in combination with heel counters and toe leathers.

The features of the shoe of this invention provide a comfortable, well-fitting fit, weight and flexibility, and stability against overpronation, combined with unique support for the foot, particularly the ankle.

Minor changes may be made to the assembly without departing from the inventive concept. Accordingly, the invention is limited only by the scope of the claims.
