New Balance FuelCell SuperComp Trainer v3 — Marathon Training, Meet Your Match

The New Balance FuelCell SuperComp Trainer v3 is built for the long haul — a half- and full-marathon training shoe that brings race-day technology to the miles that matter most. A propulsive FuelCell midsole, a carbon fibre Energy Arc plate and an angular midsole design combine to create a shoe that pushes back with every stride, keeping legs fresher and energy higher across the kind of training blocks where consistency is everything.

The FuelCell foam midsole — incorporating approximately 3% bio-based content from renewable resources — delivers a propulsive, forward-driving feel underfoot. Working with it is the Energy Arc: a carbon fibre plate with sport-specific geometry paired with strategic midsole voids designed to increase stored energy and deliver a higher amount of total energy returned. The result is a plate-assisted ride that feels lively and responsive without the stiffness of a race shoe, keeping the sensation of speed across high-mileage weeks.

An angular midsole design reduces overall weight without compromising the cushioning stack, keeping the shoe light enough for faster efforts whilst remaining comfortable across longer distances. The outsole is designed for superior traction on road surfaces, and a soft, plush mesh upper maximises breathability and comfort during sustained efforts — structure where you need it, airflow where you don't.
