A shoe insole formed by a resilient base piece adapted to be disposed primarily at the heel area and having a cupped peripheral wall. A heel piece is disposed within the base piece and constructed for improved shock absorption at the heel. A top cushioning layer is provided and overlies the resilient base piece and heel piece. The top cushioning layer extends over the base piece from the heel area thereof and forwardly of the base piece so as to principally underlie the toe area. The resilient base piece front edge includes at least a segment thereof that terminates at the large toe joint.

RELATED APPLICATION
This application relates to co-pending application Ser. No. 07/340,751, filed Apr. 20, 1989.
A footwear pad comprises a resilient layer of a plastic foam material, a protective layer of a wear-resistant cloth and adhered to the upper surface of the resilient layer, and a magnetic layer made of a magnetic rubber sheet and provided with magnetism which is distributed uniformly and unidirectionally so as to stimulate effectively the blood circulation in the feet of a user of the footwear pad.

The invention relates to a process for the manufacture of an orthopedic sort in shoes, in the case of which the top-part is provided along its borders with a continuous cut-out section, so that for the final form-imparting processes of the orthopedic support, merely a border-part and a bottom-part have to be subjected to the grinding operations. This ensures that, also after longer usage, the orthopedic support shows a stability of form, since a material thickness of only a small order of magnitude has to be subjected to the grinding operations, and in that consequently, the border-sections in the upper region of the orthopedic support, retain their retractility.
An orthotic insert having an angled lateral surface that engages the insole so as to pivot the insert in a lateral direction and invert the rearfoot at heel strike, and a medial bottom surface that freely interfits within the heel counter and insole of the shoe so as to avoid limiting pivoting motion in the medial direction as the weight on the foot shifts forwardly and medially. Pivoting motion in the medial direction is arrested by engagement between a distal medial portion of the rigid plate member and the insole along the transverse plane of the shoe. The distal medial portion of the plate member is located generally proximal and beneath the first metatarsal head of the foot. The upwardly angled medial surface of the post permits the post to fit optimally within the heel area of the shoe and also avoids interference between the heel counter/insole and the post that would impair proper operation of the insert.
A cup-like insole includes a body of elastic material having a bottom surface which has a shape to fit to a bottom member of a shoe. The insole has a flat portion and a concave side wall portion formed integrally therewith extending from the area corresponding to the inner arch portion of the foot to the area corresponding to the outer lateral side of the foot through the area corresponding to the heel portion of the foot. An impact cushioning material has bouncing putty and is disposed on the upper surface of the side wall. A sheet made of either woven fabrics, unwoven fabrics, or leather covering over the impact cushioning material secures the material to the body. The cup-like insole, according to the invention, provides improved fitness of the heel portion of a shoe to stabilize the heel of the wearer.
The present invention pertains to a resilient shoe insole. The shoe insole is comprised of a resilient material having sufficient thickness in the heel and forefoot region to allow the resilient material to act as a spring, thereby absorbing the impact of a foot and then returning at least 70% of absorbed energy to the foot thereon and providing increased lift and response to the foot and reduced O.sub.2 demand in running relative to other insoles for a given activity. In a preferred embodiment, the shoe insole has a heel portion and a forefoot portion, wherein the heel portion is thicker than the forefoot portion. The heel portion is at least 3/8 inch thick and the forefoot portion is at least 1/4 inch thick. In another embodiment, the base is comprised of multiple laminations of the resilient material. In another preferred embodiment, the shoe insole is comprised of a wedge-shaped heel pad comprised of a resilient material which absorbs the maximum impact of the heel of the foot and then returns 70% of absorbed energy to the heel; the heel pad is adapted to fit under a standard sockliner of an athletic shoe and is at least 3/8 inch thick. The heel pad is wedge-shaped with at least an 8.degree. taper such that each step causes the foot to be thrust forward.
