Metaspeed Edge Tokyo vs Metaspeed Sky Paris

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.

The Metaspeed Sky Paris is ASICS at full race trim: a carbon racing shoe built for one job, chasing a personal best on the road. It is the cadence runner's racer, the half of the Metaspeed line tuned for runners who get faster by keeping their stride length and turning their legs over quicker, while the Metaspeed Edge Tokyo handles those who lengthen their stride. At 215g with a full-length carbon plate and a 5mm drop, it is light, aggressive and unmistakably a marathon shoe rather than a do-everything trainer. The bouncy, springy foam and stiff plate work together to roll you forward and reward a committed effort. Hold goal pace and it comes alive. Jog it easy and you will wonder what the fuss is about. In our view it sits right at the top of the carbon racing shoe pack alongside the Nike Vaporfly 4, and at £260 it is priced like the elite tool it is.
