Utilizes Dupont’s™ premier Kevlar® knit fabric. The one piece liner eliminates overlapping seams that trap moisture and channel burning steam. Allows generous layers of insulating materials to fit inside the toe cap to reduce conductive heat. Separation from the foot via midsole insulation reduces temperature penetration. Dual-purpose design is textured for stability and cushioned for comfort. Vulcanized patches retain full brightness and reflectivity over time, even at high temperatures. Provides athletic shoe comfort and additional thermal protection.
