DH champs and flat pedal specialists Sam Hill and Brook Macdonald helped design the Impact VXi for gravity fed, foot out junkies. Our new STEALTH MI6 rubber outsole has 50-percent more shock absorption and damping than any other shoe on the market. Not only is it stickier than its competition but it also dampens impact as you smash through rock gardens. The upper on the new Impact has been slimmed down but provides more protection than the original, while shaving 25-percent off the weight. Plus we’ve added a quick-dry, hydrophobic upper that dries overnight.
