Lighter than the 6th version the Fresh Foam X Hierro v7 GTX Trail Running Shoe lets us tackle trail runs with confidence. The Vibram Megagrip traction shows off on most surfaces letting us run with reckless abandon when it's wet or dry muddy or rocky. New Balance's Fresh Foam X midsole features light cushioning to absorb shock while the GORE TEX membrane fights off water while releasing sweat vapor to keep us comfortable on soggy trails.
