The Impact Phenom Racing Shoe was developed using feedback from Impact’s professional drivers who expressed a need for a comfortable lightweight driving shoe suitable for all track conditions, including dirt and mud. Featuring a very soft, tanned calf leather exterior, the Phenom RS provides the ultimate in comfort, while resisting mud and dirt build up. Using our next generation, preformed anatomic sole made of pure lightweight rubber; the Phenom RS provides an incredible driver/vehicle interface experience. The Velcro® strap closure and Speed Laces ensure the ultimate in support and adjustability, and the Achilles stretch panel greatly enhances mobility and comfort. The Phenom RS is available in Black or White, in US sizes ranging from Men’s 7 to 13. Phenom RS is SFI approved.
