Rain or shine. Street to summit. Built at the intersection of road and trail, the Challenger 7 GTX has been completely reimagined from the ground up. Combining a simplified mesh upper with a soft new foam, we’ve increased the stack height for a plusher feel and added GORE-TEX INVISIBLE FIT with recycled content product technology for enhanced protection in inclement weather. Inspired by gravel tires, we’ve cued up smaller, tightly spaced lugs in center and larger, more aggressive lugs at the perimeter designed for improved traction on uneven terrain.
