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.

The Puma Deviate Nitro 4 is a carbon-plated do-it-all running shoe, and that is the point of it. Puma pitches this as one pair for almost everything: easy miles, tempo work, long runs and the occasional race. At 245g it is heavier than a pure marathon shoe, but that weight buys you a plush, durable ride you can rack up training miles in without babying it. The carbon plate sits under a tall 33.6mm heel and a 7mm drop, so you get a smooth, propulsive roll rather than the aggressive snap of a race-day shoe. In our view this is the sweet spot for one runner who wants a single versatile trainer instead of a rotation. It rewards a controlled tempo more than a flat-out sprint. If you want the widest use per pound at £150, few carbon shoes are as adaptable. The Saucony Endorphin Speed 5 is the obvious rival, and it is lighter, but the Deviate feels the more robust daily companion.
