The UltraGrip sole is the premium in slip and fall protection on wet and dry floors. The sole material is clean, durable and strong enough to stand up to even the most abrasive floor surfaces. The proprietary Microbreathe™ material used in the upper portion of the boot cover is soft, strong, and flexible with a high vapor transmission rate for all day comfort while providing excellent barrier protection and particle holdout. UltraGrip boot covers are static dissipative for those applications where electro-static dissipative (ESD) protection is required.
