New Balance Fresh Foam X Hierro V9 Women's Trail Running Shoes

New Balance Fresh Foam X Hierro v9 is a trail running shoe designed for long distances on gravel, trails, and soft surfaces where substantial cushioning and stability are needed. It features a lightweight, breathable upper with synthetic reinforcements and a gusseted tongue to keep gravel out. The midsole uses Fresh Foam X in a dual-density construction, with a softer top layer for comfort and a firmer bottom layer for stability on uneven terrain. Toe Protect helps shield the toes from rocks and roots, while the outsole uses Vibram Megagrip with traction lugs to provide grip on wet and dry surfaces. The shoe is intended for long trail runs, ultramarathons, and fast mountain runs, and incorporates sustainability by embedding bio-based materials into the Fresh Foam X midsole alongside other performance characteristics.
