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 has increased the stack height for a plusher feel and added proprietary rubber to the bottom unit, along with a reimagined outsole design for the best all-terrain ride yet. Inspired by gravel tires, HOKA have cued up smaller, tightly spaced lugs in center and larger, more aggressive lugs at the perimeter designed for improved traction on uneven terrain.
