Built for the trails and designed for performance, the Hoka One One Challenger ATR 7 will take you across any distance in unmatched comfort. Continuing the success of it's predecessor, it's strategic midsole construction utilises compression moulded EVA foam for increased impact absorption, and added spring at toe-off. The reimagined outsole combines tightly spaced lugs in the centre, with larger, more aggressive lugs at the perimeter for improved traction on rocky / uneven terrain.
