FuelCell SuperComp Elite v5 vs Deviate Nitro Elite 4

The FuelCell SuperComp Elite v5 is New Balance at its most serious: a carbon marathon racing shoe built to chase a personal best on the road and nothing else. This is a full super-shoe, with a PEBA midsole and a carbon plate that New Balance says is 38 per cent stiffer than before, and at 213g it is genuinely light for a shoe carrying this much foam. That combination is the whole point. You get a tall, energetic stack that protects your legs deep into a marathon, and a plate rigid enough to snap you onto your toes when you hold race pace. It sits right at the top of the road racing market on price at 220 pounds, up against the Nike Vaporfly 4 and the rest of the carbon crowd. We rate it as a true race-day tool. It rewards a committed effort and feels flat if you jog. Buy it to race, not to train.

The Deviate Nitro Elite 4 is Puma's mainstream carbon racing shoe, the one most runners should look at before the pricier top-tier Fast-R. It sits in the same road-racing class as the Vaporfly and the Adios Pro, a plated marathon shoe built to hold pace when your legs start asking questions. For this fourth version Puma went firmer, with a reworked ATPU midsole under a carbon plate, so the ride feels more planted and direct than a soft, tippy super shoe. Where it really separates itself is the PUMAGRIP outsole, which is genuinely excellent in the wet and gives you confidence through corners that many racers cannot match. At £215 it is priced right alongside its rivals, so this is a straight race-day tool, not a do-everything trainer. If you want a stable, grippy carbon racing shoe for half and full marathons and you like a firmer, propulsive feel, we rate it highly. Chase a softer, bouncier ride and you might prefer the Vaporfly 4.
