New Balance FuelCell V3 - White First, the New Balance FuelCell V3 - White is New Balance's fastest shoe in its cleanest form. White on nitrogen-infused FuelCell foam and a full-length carbon plate — the color of clinical preparation and complete readiness. Moreover, this is the FuelCell for runners who trust their preparation entirely. The neutral colorway for athletes who let their finish time speak. FuelCell (Nitrogen-Infused) + Carbon Plate: New Balance Racing Technology Additionally, fuelCell foam is nitrogen-infused — a process that creates a lighter, more responsive foam cell structure than standard EVA. The result is a midsole that returns energy with a snap that builds across marathon distance. The full-length carbon fiber plate amplifies that return, creating a propulsion system that rewards runners who push consistently from start to finish. Engineered mesh upper: lightweight race fit. Rubber outsole. 215 g. 6 mm drop. 38 mm heel stack. New Balance's most technically advanced racing platform. For Who? For New Balance runners targeting marathon and half-marathon PRs. Best for athletes with race-shoe experience who know their goal pace.
