Adizero Adios Pro Evo 3 vs Metaspeed Edge Tokyo

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.

The Metaspeed Edge Tokyo is ASICS at its sharpest: a 159g carbon racing shoe built to chase a personal best on the road and not much else. It is the Edge, so it is tuned for cadence runners, the people who get faster by turning their legs over quicker rather than by reaching for a longer stride. If that is you, the geometry here works with you instead of fighting you. At 38.9mm in the heel and a 6.9mm drop it sits right at the front of the modern marathon shoe pack, and the carbon plate gives you a firm, snappy platform that wants to roll forward. This is a race-day tool, not a do-everything trainer. Step on at easy pace and it feels stiff and a touch unforgiving. Hold goal pace and it comes alive. If you lengthen your stride to find speed, look at the stride-biased Metaspeed Sky Paris instead. At £230 it is a serious outlay, so be honest about whether you will use it.
