Impacts SFI 3.3/20 shoe quickly became the standard for the ultimate in drag racing footwear protection. Upping the ante for 2020, Impact introduces the Nitro Drag shoe. Ideal for nitro and alcohol-powered racecars, the Nitro Drag is constructed with supple calf-skin leather outer, and an ultra-plush meta-aramid interior. In addition, the Nitro Drag is almost 20% lighter than its predecessor. The new, ultra-thin oil-resistant and anti-static sole also makes for the ultimate in driver/vehicle interface, providing superior pedal feel and control. The Nitro Drag also offers a deep Achilles cut-out for maximum range of motion and finishes with a hook and loop ankle strap for greater support. This is one SFI 3.3/20 rated shoe you will not want to take off! Available in Black, US men’s sizes 7-13.
