Trail2025 · Global · ReleaseChecked 2026-10-06

Fresh Foam X Hierro v9 is a cushioned trail model with a redesigned tread and deeper, approximately 6 mm lugs. Its dual-density Fresh Foam X midsole places a softer layer over a firmer base. Vibram Megagrip supplies trail grip, while a breathable knit-mesh upper, gusseted tongue, printed overlays and Toe Protect help manage loose debris and abrasion. Standard through extra-wide widths vary by market.
