The Impact Racing Axis series high-top driving shoe is constructed from a suede outer liner with a fire retardant inner to meet SFI 3.3/5. This shoe is very similar to the Racequip 305 series boots but these shoes from Impact have a higher build quality and are more fitted. We'd consider this boot a "mid-tier" shoe due to it's robust construction and because they are very comfortable. If you are planning on heel-toe shifting we'd recommend you go with a mid-top boot like the ZAMP ZR-50, another mid-tier shoe, to help with mobility.
Expect these to be stiff through the break in period as they are multi-layer shoes. Your shoe size should be used for selecting the correct size.
