The GF235 race shoe is our most popular and is built with top quality suede leather and an exclusive RaceGrip sole. The shoe is lined with fire-retardant cotton to keep your feet cool in hot racing conditions and extra comfort is provided by a RaceGrip innersole with arch support. The RaceGrip sole is manufactured from a high grip rubber compound and its low-profile beveled sole that keeps the shoe from catching on the pedals. SFI 3.3/5 certified.
