This versatile hybrid with an aggressive rubber sole has the fit of the popular Barefoot collection: the design mimics the shape of the human foot so that it assumes its natural barefoot position even when wearing shoes. Upper material: pigskin. Traditional lacing with metal hooks. Full-length tongue to prevent dirt from getting in. Breathable mesh lining. Thanks to the Merrell Barefoot 2 construction, the foot adopts a natural position. Mountain-compatible Merrell Quantum Grip rubber outsole. Drop: 0mm.
