The New Balance FuelCell SuperComp Elite v5 is the company's clearest swing yet at the marathon-day super-shoe market. It lands at £230 in the UK and $265 in the United States, sliding in just below most of its peers but ahead of the brand's own previous flagship. The biggest changes are not on the spec sheet but underfoot: a more aggressive carbon plate sits inside a narrower, more race-tuned platform, and the heel-to-toe drop has jumped from 4mm to 8mm, dragging the v5 firmly back toward pure racing after a v4 that some testers felt drifted into long-run-trainer territory.
Out of the box, the v5 feels firmer and quicker than its predecessor without losing the cushioned signature New Balance has been chasing across this line. The PEBA-based FuelCell midsole stacks 40mm in the heel and 32mm in the forefoot, and the engineered mesh upper trims weight without sacrificing the lockdown that has been a SuperComp strength since the v3. New Balance has retained the wide fit and added a new extra-wide option, which materially expands the audience for a category that has too often catered only to narrow forefoot runners. Reviewers report a more locked-in toe-box than the v4 with the same heel architecture.
The ride is where the v5 makes its case. The firmer foam and more decisive plate produce an unmistakable propulsive snap at marathon pace, with the centre of gravity riding visibly further forward than the outgoing model. The narrower midfoot and slightly squared-off heel geometry add a degree of stability that is unusual at this stack height; multiple test publications have called the v5 one of the more stable carbon-plated racers on the market, a useful trait for the second half of a marathon when fatigue starts to expose any wobble in the platform. The trade-off is that the shoe is less forgiving on slower days than the v4 was, and reviewers consistently say it is not a shoe to use as a daily trainer.
For runners deciding between the v5 and its fiercest rivals, the picture is becoming sharper. Against the Nike Vaporfly 4, the New Balance offers more cushion and stability for marathon distance while ceding a touch of agility under 10K. Against the Adidas Adios Pro Evo 3, the SuperComp Elite v5 is heavier and wider but several times more durable and dramatically cheaper. The middle of the field, including the latest Asics Metaspeed and Saucony Endorphin Elite, is where the v5 will compete most directly: the call there comes down to fit and ride preference rather than any clear performance gap.
New Balance is positioning the v5 squarely as a race-day investment rather than an all-rounder, and reviewers across the spring marathon season have largely accepted the framing. Expected outsole life sits around 200 to 300 miles before notable wear, in line with the rest of the super-shoe category. For runners targeting an autumn major or a summer half-marathon block, the v5 is the most assertive racer New Balance has ever sold under the FuelCell banner, and a strong reminder that the brand intends to be in the marathon super-shoe conversation rather than around its edges. It is on sale now through New Balance's direct channels and major specialist retailers.
