Dielectric Overshoes are made from yellow ozone resistant rubber that’s 100% waterproof. The construction is hand-layered in full-cut patterns to easily slip over work shoes. The lining is fabric so they easily slip on and off. These overshoes meet ANSI Z41 standards and are tested to 14,000 volts. The 11” 4-Buckle has an anti-skid bar tread sole and heel.
