The men's Hoka Challenger 7 GTX is a versatile shoe designed for both street and trail use. It has been completely redesigned with a simple mesh upper and soft new foam for a plush feel, and features GORE-TEX INVISIBLE FIT technology with recycled content for weather protection. The sole is inspired by gravel tires, featuring smaller, closely spaced lugs in the center and larger, aggressive lugs at the perimeter for improved traction on rough terrain.
