FOX Union Boa Flat Cycling Shoes - Black, EU 44

At the trailhead, you're kitted up and ready to drop into a long enduro descent. The FOX Union Boa Flat shoes keep your feet locked onto the pedals with an Ultratac™ rubber outsole and an engineered lug pattern that bites into flat pedal pins. Dual Boa® Li2 dials let you micro-adjust fit on the fly, while a hook-and-loop power strap locks the forefoot. The welded synthetic leather and TPU upper shrugs off rock strikes, and the molded toe cap and reinforced heel counter protect against impacts. Perforated zones channel air to keep feet cool when the climb heats up. A low-profile custom-tuned EVA midsole and reinforced internal shank deliver pedaling efficiency without sacrificing walkability.
