New Balance Summit Unknown v2

Built for trail runners who like to keep the pace honest, the New Balance Summit Unknown v2 blends a race-day attitude with just enough protection to confidently attack rough ground. Its lively REVlite midsole delivers a snappy, responsive feel that stays nimble on climbs and quick changes of direction, while trail-specific defenses help take the edge off sharp rocks and roots. A breathable, quick-draining upper keeps things comfortable when the route turns wet, and the grippy outsole is tuned for confident footing on slick surfaces.
