Impact Racing Phenom driver shoes were developed with extensive feedback from Impact’s professional level drivers. Phenom shoes provide a comfortable lightweight driving shoe perfect for all track conditions, even in the dirt and rain! The soft, tanned calf leather exterior not only gives you the most comfort, but it is also excellent at resisting mud and dirt build up throughout races.
