Our Verdict
adidas Adizero Adios Pro 4
ASICS METASPEED RAY
The ASICS METASPEED RAY and adidas Adizero Adios Pro 4 are both top-tier marathon racing shoes, but they differ significantly in feel and performance. The RAY is much lighter and delivers a more efficient ride thanks to its highly energetic FF Leap foam and partial forefoot plate, which create a consistent bounce from start to finish. The Adios Pro 4 uses full-length carbon-infused EnergyRods to add stiffness. While the adidas still offers strong cushioning, the ASICS is noticeably softer and retains its protection capabilities more consistently over long distances
. However, the Adios Pro 4 offers stronger lateral stability, which also makes it a compelling marathon option.
