Our Verdict
ASICS METASPEED RAY
ASICS METASPEED SKY TOKYO
The ASICS METASPEED RAY is a better racing shoe overall than the ASICS METASPEED SKY TOKYO. It's lighter, more cushioned, and bouncier, while offering essentially the same energy return. The SKY TOKYO is much less soft underfoot and provides more assistance through the stride, making toe-off more forceful and controlled. Get the RAY if you want maximum cushioning and minimum weight; get the SKY TOKYO if you prefer more propulsion and a firmer feel underfoot.
