Designed to bridge the gap between road and trail, the Challenger 7 GTX has been completely reimagined. Combining a simplified mesh upper with new soft foam, we've increased the sole height for a more comfortable feel and added GORE-TEX INVISIBLE FIT technology made with recycled materials for enhanced weather protection. Inspired by gravel tires, we've placed smaller, closely spaced knobs in the center and larger, more aggressive knobs around the perimeter to improve traction on rough terrain.
