Racer for stride runners
Asics Metaspeed Sky Tokyo
Asics splits its racers by how you run rather than how fast. The Sky is for runners who get quicker by lengthening the stride, and this one carries the new FF Leap foam.

The shoe
Asics sells two racers and asks how you run rather than how fast. The Sky is for runners whose stride lengthens when they speed up, the Edge for runners whose cadence rises. Inside, a flat carbon plate splits two foams: the bulk of the midsole is FF Leap underneath it, with a thin layer of firmer FF Turbo Plus above so the landing stays steady. That is 39.5/34.5mm of stack, a 5mm drop, and 170g, with AsicsGrip under the forefoot.
What the foam actually is
2 layers
Bottom layer, under the plate
FF Leap
ATPU, aliphatic thermoplastic polyurethane
Thin top layer, above the plate and under the foot
FF Turbo Plus
PEBA, polyether block amide
- Plate
- carbon plate, flat rather than curved, sitting higher in the stack than the Sky Paris
- Energy return
- 78.5% heel, 78.2% forefootLab measured by RunRepeat
The bouncy layer sits below the plate and the firmer one above it, which is Asics buying landing stability with the older foam. FF Leap is the same A-TPU that softened the Superblast 3, and Asics rates it 15 percent lighter and 30 percent softer than the FF Turbo Plus it sits under.
