The New Balance Fresh Foam X Hierro v9 GTX is a men's trail shoe built for long distances and technical terrain. The upper combines lightweight mesh with synthetic overlays and an integrated GORE-TEX membrane that keeps moisture out without sacrificing breathability. The dual-density Fresh Foam X midsole pairs a softer top layer for comfort with a firmer bottom layer for stability, while the Vibram Megagrip outsole with Traction Lug delivers grip on wet, muddy and rocky ground. A Toe Protect cap shields the toes from rocks and debris, and the 4 mm heel drop keeps the ride close to the ground.
