The fit is so comfortable, you'll probably forget we built it with fire retardant leather and self-extinguishing split suede. But we did, along with everything else the pros demanded. That includes the fire shielding of patented CarbonX, a synthetic that outperforms all NFPA 2112 standards for flame resistant garments. For tactile response, the 3-D anatomical construction includes a high-grip outsole that gives you a responsive feel of the pedal.
