Adizero Adios Pro Evo 3 vs SuperComp Elite 6

The Adizero Adios Pro Evo 3 is a running shoe with one job: get you to a marathon finish line faster than anything else you own. At 99g it is barely there on your foot, and that sub-100g weight is the whole point. adidas has stripped away everything that does not make you quicker, then leaned on a firm ENERGYRIM perimeter to hold the shape and snap the shoe through toe-off. The result is a pure marathon shoe that feels less like footwear and more like a piece of race kit. It sits at the very top of the market on price, and it is not built to soak up your training miles. We rate it as a specialist race-day tool for runners chasing a personal best who already know their legs can handle a light, aggressive ride. If that is you, few road racing shoes feel this fast. If it is not, the Vaporfly 4 or adidas own Adios Pro 4 give you most of the speed with far more shoe underfoot.

New Balance swapped almost everything under the foot for this version, and reviewers noticed. The SC Elite v6 gets a new foam, a reworked carbon plate and a big cut in weight, and most testers called it a clear step up from the SuperComp Elite v5, which one reviewer had found closer to a trainer than a race shoe. It's now a proper carbon racer, light and springy, with a front end that won't bend. Where it works best is less settled. Doctors of Running's two testers graded it A and A-, and one would race it anywhere from 5K to the marathon. RTINGS was cooler on the long stuff, finding the forefoot cushioning only just enough for a full marathon and rating it higher for shorter races. So if you're quick and land on your midfoot, it's a strong marathon shoe. If you land on your heel and want protection in the last few miles, a softer racer will look after your legs better. At £230 RRP it sits with the most expensive racers, so check the price table before you buy.
