Designed for both the road and the trail, the new Challenger 7 has been completely redesigned. Combining a streamlined mesh upper with new soft foam, we increased the stack height for a more comfortable feel and added proprietary rubber to the lower unit, along with a reinvented outsole for a better all-terrain ride . Inspired by gravel tires, we placed smaller, closely spaced lugs in the center, and larger, sharper lugs on the perimeter, to improve grip on rough terrain.
