Abstract: An improved protective shoe. The shoe may be an industrial or athletic shoe. A protective cover overlies the toe and instep and is at least partially removeable from the shoe itself. The protective cover has an outer flexible sheet and an inner energy-absorbing layer. A particular improvement lies in providing a flap overlying the shoelaces, with a pair of openable flap closure means on each side of the flap so as to provide an unbroken cushioned surface over the very vulnerable high point of the shoe.
