An ice-gripping sandal for securement to the sole of a boot or other primary footwear. 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. This arrangement enables material which may tend to adhere to the sole within the grooves to be forced out of the grooves when the wearer walks. Other grooves in the sole serve a similar function. The toe strapping assembly includes plural flexible straps which produce a toe box for receipt of the toe of the boot to secure the toe portion of the sandal's sole to it. The toe box is adjustable to the size and shape of the toe of the boot. The heel strapping assembly includes plural straps for securing the heel portion of the sandal's sole to the heel of the boot. The straps of both of the strapping assemblies include VELCRO? fastening strips to effect the releasable securement of various of the straps together.
