Adizero Adios Pro 4 vs Adizero Adios Pro Evo 3

The Adizero Adios Pro 4 is adidas at its most focused: a carbon marathon racer built to chase a personal best and little else. At 188g it is light for a shoe with this much stack, and the EnergyRods give it a firm, forward-tipping snap that wants you up on your toes and moving. Pair that with a high, responsive midsole and you get a ride that protects your legs deep into a race while still feeling fast. It is happiest on smooth tarmac at marathon and half pace, where a quick, efficient cadence unlocks the best of it. This is not a do-everything trainer, and it does not pretend to be. If you want one shoe for easy miles and race day, look elsewhere. But if you are after a sharp, single-minded racer for the days that count, the Adios Pro 4 is one of the best around.

If you want a lighter, softer ride for the same job, the Nike Vaporfly 4 is the obvious rival.

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.
