ASICS Metaspeed Sky Tokyo Reviews

They ran their fastest half and 10k in the Sky as a heel striker, but beyond about 15k it felt unstable, their ankle collapsed in race photos and was sore for weeks. They now keep it to 10K at most.

They raced a sub-3 marathon in the Sky Tokyo and felt it suited their forefoot strike, though they thought the Edge might have fit their high cadence better.

They felt the Metaspeed Sky Tokyo was perfect and ran 2:53 in it at Boston versus 2:57 in the Alphafly 3 the year before with similar training.

Scores 7.3. It balances cushioning and reactivity, so it doesn't tire you out while returning energy with every step (energy return 8). The plate gives a decisive forward push. Estimated life is 350–400 km, and FF Leap seems to wear faster than FF Turbo.

A shoe that cuts time, for runners who lengthen their stride. The new midsole makes it usable by more runners, and once up to speed it pulls you forward. It demands leg strength to keep compressing the foam over 42 km, and the arch is pinched hard.

FF LEAP makes it lighter (~160 g at 27.0 cm) with more rebound and cushioning. After running both, he prefers it for its rebound and propulsion. Sizing at foot length +1.0 cm worked.

A cadence runner (191 spm) amazed by how much the cushioning and rebound have evolved: at 4:05–4:15/km the shoe widens your stride for you. When he faded to 5:00/km late on, it suddenly felt like a hard board. Not a magic shoe for everyone, but he will race Kobe in it.

Light and propulsive, with rebound that leaves your legs fresh late in the race. The fit and breathability are excellent. It is slightly unstable on corners and rough roads, and durability is low: the toe and heel were gouged by ~150 km. He recommends saving it for goal races.

One tester preferred the Edge in earlier generations but now prefers the Sky. The tongue is a thin flap that folds over easily, and choosing between Sky and Edge remains confusing.

Outstanding, possibly PB-worthy, for stride-style mid/forefoot strikers who want something fast and fun. The rearfoot is still too soft and unstable for heel strikers or heavy pronators over longer distances. Best for 5K to half marathon.
