Abstract
Abstract A shoe for athletics comprising an upper, a sole portion, a heel portion and cleats secured to the sole and heel portions. The upper comprises an inner side made of an elastic material and an outer side made of a substantially inextensible material. Both inner and outer sides are secured to the sole and heel portions and provide a shoe which snugly fits the player. When the player is hit by a substantial impact force the inner side expands, absorbing energy from the force and allowing the foot to move laterally out of the shoe over the sole and heel portion to reduce injury.
