The Hightop Shoe is a new take on Simpson Racing's classic style with a high-top design and satin suede upper, it's also SFI approved. The inner fleece lining is fire retardant. There is a triple layer anterior toe area for added wear protection with additional reinforcements in the heel and lace guard with double speed-fit closer. The outer sole is a non-slip, super-sensitive polyurethane sole with posi-grip traction.
