Metaspeed Edge Tokyo vs Endorphin Elite 3

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 Endorphin Elite 3 is Saucony's no-compromise carbon racing shoe, built for one job: chasing a personal best over the half and full marathon. This is a specialist marathon shoe, not a do-it-all trainer. You get a tall 40mm heel, a full-length carbon plate and Saucony's springy IncrediRUN foam, all wrapped up at a race weight of 210g. At £306 it sits right at the top of the market, alongside the Nike Alphafly 3 and the adidas Adizero Adios Pro 4. What you are paying for is peak return at speed. The slotted plate and high stack give a rolling, aggressive ride that wants to move. It is less versatile than Saucony's own Endorphin Pro 5, and it asks for a fair bit of leg strength to get the best from it. We rate it as one of the sharpest tools you can lace up on race day, so long as race day is what you want it for.
