Abstract: An athletic shoe is disclosed. The athletic shoe includes an upper attached to a sole. The upper has a forepart section comprised of an inner layer and an outer layer. The inner layer is preferably formed of relatively thin stretchable leather and the outer layer is formed of a breathable nonstretchable material, such as nylon mesh. A slight gap is formed between the outer surface of the inner layer and the inner surface of the outer layer to allow the inner layer to stretch a limited degree in order to mold to the forepart portion of the foot of the wearer of the shoe.

Abstract: Curved last soles for athletic shoes are disclosed, including one embodiment wherein cleats are arranged with gripping edges in the arch and heel that are perpendicular to the longitudinal axis passing therethrough, whereas in the toe cleats are arranged with gripping edges that are aligned in rows that are perpendicular to a line generally defining the direction of travel while the athlete abducts his or her feet during the propulsion phase of running. Cleats in the ball portion of the sole fan out to provide a smooth transition from the cleats in the arch to the cleats in the toe.In a second embodiment the cleats are disposed throughout the sole in rows which maintain a perpendicular relationship relative to the longitudinal axis of the heel, but the orientation of the gripping edges of the cleats in the toe and ball portions are varied in such manner as to compensate for the aforementioned abducting effect.

Abstract: A general purpose athletic shoe is described in which an outer sole is provided with integrally molded cleats of two different types. The cleats of the first type are disposed around the periphery of the sole and the cleats of the second type are primarily disposed in the remaining portions of the sole. The second cleats are generally conical in shape and extend outwardly from the sole to about half the height of the first cleats. Each of the first cleats has three surfaces extending outward from a major exterior surface of the outer sole to a flat crown which is parallel to the major exterior surface. Two of the three outwardly extending surfaces of each of the first cleats take the form of essentially flat surfaces oriented generally perpendicular to the major exterior surface and the remaining outwardly extending surface is a partial conical surface which tapers so that first cleats are widest at their junction with the outer sole and narrowest at the crown.

Abstract: An athletic shoe is described including a shoe upper having a toe section and a main body section joined together and to a sole portion. Preferably the toe section extends forwardly of the metatarsophalangeal joints and is of a stretchable material to permit flexing of toes within the shoe, while the main body portion is of a nonstretchable material to restrict pronation of the rest of the foot. When the shoe is laced, first and second external reinforcing strips on the medial side of the upper, respectively exert pressure on the forward and rearward sides of the ball of the foot to restrict its motion. A third such strip on the other side of such upper limits the motion of the fifth metatarsophalangeal joint and urges the ball of the foot between the first and second strips. The first and third strips also join the toe and main body sections together without these sections overlapping.
