People love the idea of adventure in the great outdoors, but there’s more to the natural landscape than fresh air and scenic views. Uneven terrain, debris, and moisture are unique challenges to footwear that require specialized construction. For those who take going off the beaten path literally, there’s the Fresh Foam X Hierro, a dedicated, off-road application of our best running technology. The Fresh Foam X Hierro v8 employs a Vibram® Outsole to create a protective shell of durability and traction around the signature Fresh Foam X cushioning and a breathable, lightweight upper.
