Abstract
An ice-gripping sandal for releasable mounting on the foot of a person or on the sole of a boot or other primary footwear worn by the person. The sandal comprises a sole, a toe strapping assembly and a heel strapping assembly for mounting the sandal on the boot. The sandal's sole has a bottom surface having plural groups of cleats projecting therefrom. Some of the cleats are located within a forefoot and toe portion of the sole and extend at an acute angle to the longitudinal axis of the sole. These cleats include end portions having respective ice-gripping screws mounted therein. Grooves are provided between the cleats in the forefoot and toe portions of the sole, with the width and depth of the grooves increasing from the medial side of the sole to the lateral side of the sole. The grooves enable material which may tend to adhere to the sole within the grooves to be forced out of the grooves when the wearer walks. In order to increase the flexibility of the sole plural recesses are provided in the arch region contiguous with the forefoot portion.
