A novel shoe structure, particularly a ballet shoe, is provided in which an elongate flat leaf spring element is provided associated with the sole of the shoe structure. The elongate leaf spring extends from the toe region of the shoe structure beyond the location of the metatarsal-phalangeal (m-p) joints of the wearer, so as to provide a mechanical power assist to the wearer at the m-p joints.
