SuperComp Trainer v3

The New Balance FuelCell SuperComp Trainer v3 refines the super-trainer category with a lighter, more energized construction built for long-run comfort and daily performance efficiency. Now equipped with the brand’s newest supercritical PEBA-blend FuelCell foam—first introduced in the Rebel v4—the v3 delivers a noticeably springier ride with enhanced rebound and liveliness, making every mile feel smoother and more fluid than before.

Anchoring the midsole is an updated forked carbon plate that reduces weight while maintaining propulsion, and the signature Energy Arc channel works beneath it to generate powerful energy return and a rolling, efficient stride path. The result is a high-stack platform that feels both exceptionally cushioned and subtly aggressive, ideal for tempo days, long sessions, and everything in your weekly volume.

The engineered mesh upper with FANTOMFIT support provides lightweight structure and breathable lockdown, wrapping seamlessly at midfoot without excess bulk. Underfoot, a strategically tuned outsole adds forefoot stiffness for improved toe-off power while maintaining durability for everyday use.

Whether serving as the perfect training partner for the SC Elite or as a standalone mileage machine, the FuelCell SuperComp Trainer v3 brings elite-level comfort, efficient roll-through mechanics, and a distinctly energetic feel to any run on the calendar.
