Easy to attach; simply unzip the velcro toe and ankle straps, slip the toes under toe strap, slide the foot back firmly against rear straps and secure straps. In a word, ASTONISHING! Their uses are endless. The practical solution to that age-old problem of "TRACTION" in slippery conditions such as ICE, SNOW and SLUSH. Super Soles feature a unique design that insulates feet from the ground. The design keeps feet warmer and dryer, yet provides extraordinary grip. They use quality lightweight materials that stay flexible and have replaceable cleats assuring long life. Size Small 11 3/4" X 4 1/2" Medium 12 1/4" X 4 5/8" Large 13" X 4 3/4" X-Large 13 3/4" X 5"
