Discontinued Shoe with limited colors/sizes remaining. Please check the drop down options box on the right for current availability. Over-the-wall pit crews need uncompromising fire protection, and race veterans get it with patented CarbonX lining that exceeds all NFPA testing standards for searing heat and flame. We decided to take it further, so we armed this design with Firewall suede leather. Cutting-edge technology makes it a flame retardant, self extinguishing, oil resistant feat of engineering. Loaded with innovations, this crew-tested gear is footwear for firestorms. The low profile optimizes agility while maintaining the level of stability and tactile response that the gas man and the rest of the crew demand.
