Abstract
An item of footwear, in particular for sport, includes a sole, a double-crossbow shaped elastic structure, having an upper wall and a lower wall which define an empty space inside them. The elastic structure is placed in the sole so as to elastically react under the weight of a foot. An element extends from one of the walls and is suitable for going into abutment against the opposite wall when the crossbow structure is not compressed.
