Our Verdict

adidas Adizero Adios Pro 4

ASICS METASPEED SKY TOKYO

The ASICS METASPEED SKY TOKYO is a better racing shoe overall than the adidas Adizero Adios Pro 4. It's dramatically lighter, better cushioned, and a bit more energetic, giving it the edge for both marathon and shorter-distance racing.
