Abstract
Abstract This foot protector includes a front portion providing a protective cover for the toes and instep of the wearer and a wrap-around rear portion protecting the back and ankle portions of the foot, the protector being fully open at the bottom. The rear portion of the protector includes oppositely disposed sides extending above the front portion and the rear portion is formed into separable portions which are provided with lace openings. The upper side portions are also provided with lace openings so that the separated side portions can be laced together by a single lace which extends around the ankle to draw the sides together and secure the protector to the foot. Reinforcing strips are provided to strengthen the lace margins and the junction between the front and rear portions of the shoe.
