6325 Spikeless Traction Devices reduce the risk of slips and injuries by providing spike-free traction on slick surfaces, particularly water, snow and slush. These shoe and boot grips are designed for work environments where spiked ice cleats are not preferred for a safe, easy transition between indoor and outdoor use without scratching surfaces. Soles are constructed with Soles by Michelin (SBM) ice and outdoor rubber compound - the same innovative technology found in Michelin's winter driving tires. Strategically placed grooves allow efficient water evacuation when pressure is applied, preventing water buildup. Tread is designed with block sipes that create additional surface area for increased grip on snow surfaces. Micropumps maximize adhesions by distributing pressure to maintain high surface contact on icy surfaces. One-piece, stretch design with adjustable cord cinches for a secure fit over any style of boot or shoe. Large size fits U.S. men's shoes and boots sizes 8 to 11.
