Built at the intersection of road and trail, the new Challenger 7 has been completely reimagined from the ground up. Combining a simplified mesh upper with a soft, new foam, HOKA® increased the stack height for a plusher feel and added proprietary rubber to the bottom unit, along with a reimagined outsole. Inspired by gravel tires, the smaller, tightly spaced lugs in center and larger, more aggressive lugs at the perimeter improve traction on uneven terrain.
