FuelCell Rebel 4 vs Deviate Nitro 4

The FuelCell Rebel v4 is New Balance at its most fun: a lightweight, plateless tempo shoe built to make quick running feel easy. At 212g it is properly light, and there is no carbon plate here, so the pop comes straight from a soft, springy FuelCell midsole rather than a stiff propulsion board. That makes it one of the more versatile speed shoes going. You can rip a session in it, float through a steady long run, then use it as a do-everything daily trainer the next morning. It sits in that sweet spot between a cushioned daily and a race shoe, and it does it for a fair RRP. If you want a single pair to cover most of your mileage without buying a rotation, this is a strong pick. The newer Rebel v5 has since arrived, so the v4 is often the smarter buy on price. Just do not expect the locked-in, aggressive feel of a plated racer. This one is about bounce and freedom, not rigidity.

Puma cut the Deviate Nitro 4's RRP to £150, £10 under version 3, and made it a friendlier shoe while it was at it. Reviewers agree it's the best-fitting Deviate so far: the upper has more give, and the midsole feels softer on easy runs yet still picks up when you push. Think of it as a carbon-plated daily training shoe and tempo shoe rather than a marathon racer. It sits lower than most super trainers, and on paper its 7mm drop is lower than the old model's too. What it lacks is a bit of excitement. One UK review panel liked it but felt rivals such as the Adizero EVO SL are springier, and lab testing found the heel much less lively than the forefoot. We rate it a very good all-rounder, a step behind the best in its class.
