With the men’s CHALLENGER ATR 5 Running Shoe, you get lightweight cushioning and room to move as you hit the trails or roads. The oversized cushioned midsole is a Hoka One One specialty. Dual Layered mesh at the upper supports and breathes. The 4mm lugs have been grouped at the heel and spread out up front to bite and hold in wet conditions. Speed comes first with the locked down midfoot and locked-in heel counter.
