Asics has finally pushed the Metaspeed Edge into the same FF Leap foam era as its Sky stablemate, and after several weeks in the Tokyo update we are confident the brand has resolved the principal complaint about the previous generation. Where the prior Edge could feel slappy and unforgiving once the legs began to drift past tempo pace, the new midsole compound is appreciably softer underfoot while preserving the peppy push-off that has long been the racer's signature. The shoe weighs in just under 168 grams in a UK 8.5, which keeps it inside the increasingly crowded sub-six-ounce supershoe bracket alongside the Adidas Adios Pro Evo 3 and Nike Alphafly 3.
The Edge Tokyo retains the curved, rather than spoon-shaped, carbon plate that has differentiated it from the Sky variant since the line launched in 2021. Asics's research base has long argued that cadence runners, who add steps per minute as pace increases, are best served by a smoother transition rather than a steeper rocker. Our miles on the road bear that out: the Edge feels more linear than the Sky, encouraging a quick turnover rather than the slingshot sensation favoured by long-stride runners. For 5K and 10K racing especially, that is a meaningful difference, and one we expect to translate into faster average paces for the right athlete.
Stack height sits at the legal limit of 40mm in the heel, with a 5mm drop, and the geometry has been tuned to keep the Edge as agile through corners as it is at speed on a straight. The platform widens slightly at the forefoot relative to the previous edition, which goes some way to addressing concerns that the shoe was too narrow for runners with broader feet. We still struggle to recommend the Edge to anyone whose foot measures wider than a standard D fitting, but the change is welcome and brings the model closer to the stability profile of its competitors.
Outsole grip has been improved with an updated rubber pattern that holds well on damp surfaces and shows minimal wear after roughly 80km of road racing efforts. Asics has historically been excellent on durability for a featherweight racer, and the Tokyo Edge looks set to follow that trajectory. The mesh upper is the lightest the brand has produced in the Metaspeed line and breathes well, although we would caution that the lacing can feel slightly hot-spotty over the navicular for runners with high arches. A thin tongue and minimal heel collar keep weight down without sacrificing security at race-day intensity.
At a UK retail price of £250 the Edge Tokyo is not cheap, but it is in line with the rest of the supershoe market and undercuts a handful of rivals at the top end. For cadence-driven athletes who found the previous Edge harsh in the second half of a marathon, the FF Leap update is the upgrade that finally makes the shoe a true 5K-to-marathon racer. If you are a long-strider or you favour a punchy, board-like ride, the Sky Tokyo remains the better pick, but the Edge has clearly closed the gap and is now arguably the more versatile of the two flagship Asics carbon-plate models.
