Mens Hoka Challenger ATR 7 (2E Wide) Street-approved. Trail tested. Built at the intersection of road and trail, the Hoka Challenger 7 has been completely reimagined from the ground up. Combining a simplified mesh upper with a soft new foam, Hoka have increased the stack height for a plusher feel and added proprietary rubber to the bottom unit, along with a reimagined outsole design for the best all-terrain ride yet.
