Trail2025-07 · JP · ReleaseChecked 2026-10-20

MTN Racer 4 is a high-cushion neutral trail shoe built for technical races and daily training. It retains the proven platform and Vibram Megagrip traction of its predecessor while adding an FKT insole for faster drainage and rebound, a tuned upper, and an improved gaiter attachment. ZipFoam protection, a roomy toe box, and a secure midfoot and heel support natural movement and confident footing on wet, rocky terrain.
