Street-approved. Trail tested. Built at the intersection of road and trail, the Hoka Challenger 7 has been completely reimagined from the ground up. Combining a simplified mesh upper with a soft new foam, the stack height is increased for a plusher feel and proprietary rubber added  to the bottom unit, along with a reimagined outsole design for the best all-terrain ride yet. Inspired by gravel tires, the rubber sole has smaller, tightly spaced lugs in center and larger, more aggressive lugs at the perimeter designed for improved traction on uneven terrain.
