For the better part of five years, Puma has occupied an unusual position in the carbon racing shoe market: respected enough to attract elite athletes, but never quite able to match the hype or the performance metrics of Nike's Vaporfly and Alphafly, the Adidas Adizero Adios Pro, or the Saucony Endorphin Pro. The Deviate Nitro Elite 4, which launched globally on 26 February at a retail price of £250, represents the German brand's most determined effort to close that gap. After several weeks of testing across tempo runs, long runs, and a half marathon race effort, the verdict is clear: this is a properly fast shoe that deserves to be mentioned alongside the best in the category, even if it does not quite dethrone the current leaders.
The centrepiece of the Elite 4 is its dual-layer, nitrogen-infused NITRO Elite foam midsole, which delivers a 40mm stack height at the heel — right at the World Athletics limit for road racing. Puma has paired this with a redesigned PWRPLATE, a full-length carbon fibre plate that sits between the two foam layers and provides the characteristic snappy propulsion that runners have come to expect from plated racers. The energy return figures, while not publicly benchmarked against competitors by Puma, feel genuinely competitive underfoot. There is a noticeable pop through the forefoot transition that rewards an aggressive running style, and the shoe handles the shift from heel contact to toe-off with a smoothness that the Elite 3 occasionally lacked. At 215 grams for a men's UK 9, it is not the lightest option in the category — the Nike Alphafly 3 and Saucony Endorphin Pro 4 both come in lighter — but the difference is marginal and unlikely to matter over marathon distance.
Where the Elite 4 distinguishes itself most convincingly is in its upper construction and overall fit. Puma has used a lightweight engineered mesh that wraps the midfoot securely without creating pressure points, and the internal padding around the heel collar is minimal but effective. The shoe locks down well at race pace, which is not something that can be said of every super shoe on the market. The tongue is thin and gusseted, sitting flat against the top of the foot without bunching, and the lacing system holds tension reliably across a range of foot shapes. It is a well-made racing shoe that does not require the kind of compromises — blisters, heel slip, excessive looseness — that some competitors demand.
The outsole uses Puma's PumaGrip rubber in a strategically placed configuration that covers the high-wear zones without adding unnecessary weight. Grip in wet conditions proved adequate during testing, though not exceptional — a common trade-off in shoes that prioritise weight savings over full-coverage rubber. For dry-road racing, which is the shoe's primary intended use case, traction is not a concern. The rocker geometry is moderate, sitting between the aggressive forward pitch of the Vaporfly and the more neutral profile of the Adios Pro, and suits runners who prefer to feel in control of their stride rather than being launched forward by the shoe's mechanics.
At £250, the Deviate Nitro Elite 4 is priced competitively against its direct rivals — the Alphafly 3 retails for £275, the Adios Pro 4 for £240, and the Endorphin Pro 4 for £225. The question for serious racers is whether Puma's option offers enough of an advantage to justify switching from a proven formula. The honest answer is that it does not redefine the category, but it does belong in it. Runners who have found other super shoes too unstable, too narrow, or too aggressive in their rocker profile may find the Elite 4's balanced ride particularly appealing. For Puma, that may be enough: not every great racing shoe needs to be the fastest on paper to earn a place in the rotation. Sometimes being the most reliable is its own kind of excellence.
