Adventure in the wilderness sounds very appealing to many, but nature is not all fresh air and photogenic landscapes. Uneven terrain, scree and moisture stress the footwear in every respect and require a specific construction. For those who literally venture onto untravelled paths, there's the Fresh Foam X Hierro, which moves our best running shoe technologies to the off-road realm. The Fresh Foam X Hierro v7 features a Vibram Megagrip outsole with toe protection that acts as a protective shell around the renowned Fresh Foam X cushioning for durability and grip. This is complemented by a lightweight, breathable upper.
