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 New Balance Fresh Foam X Hierro Mid, a dedicated, off-road application of our best running technology. The Fresh Foam X Hierro Mid employs a Vibram Megagrip outsole, mid-cut synthetic upper with GORE-TEX waterproof fabric, and toe protection to create a protective shell of durability and traction around the signature Fresh Foam X cushioning.
