Built at the intersection of road and trail, the Challenger 8 delivers all the smooth cushioning and confidence-inspiring traction you’ll need to tackle a variety of terrain. A gravel-grinding workhorse loved for its hyper cushy ride, we’ve added even more foam underfoot and improved the fit since our last iteration. Finished with a minimal mesh upper, plush collar, and durable rubber toe cap, we’ve reimagined the orientation of our multi-directional lugs to ensure the best all-terrain ride yet.
