New Balance FuelCell Summit Unknown v4

Built to move quickly when the trail gets unpredictable, the New Balance FuelCell Summit Unknown v4 is a nimble, race-leaning trail shoe that blends snap and protection without feeling bulky. Its FuelCell midsole delivers an energetic, propulsive ride that stays stable as you change pace, while the underfoot protection helps you stay confident over sharp rocks and roots. A secure, bootie-style upper locks you in for off-camber terrain, and the aggressive outsole pattern is tuned for grip when conditions turn wet or loose.
