New Balance FuelCell Summit Unknown v3

The New Balance FuelCell Summit Unknown v3 is built for trail runners who want a quick, connected ride on technical terrain. Designed to feel more like a race shoe than a max-cushion cruiser, it pairs a lively FuelCell midsole with a protective Rock Stop plate to keep you moving confidently over sharp rocks and roots. Underfoot, a lugged Hydrohesion outsole targets grip when trails turn wet and slick, while the snug, bootie-like upper locks your foot down for fast cornering and off-camber control.
