adidas Adizero Adios Pro 4 vs ASICS METASPEED SKY TOKYO

The ASICS METASPEED SKY TOKYO and the adidas Adizero Adios Pro 4 are both top-tier marathon racers, but they differ in design philosophy and feel underfoot. The SKY TOKYO is dramatically lighter and uses a flatter full-length carbon plate placed close to the foot for a direct, propulsive toe-off, while the Adios Pro 4 relies on its carbon-infused EnergyRods and more pronounced rocker geometry to deliver a rolling, snappy transition. Both are highly efficient, but the SKY offers slightly better energy return and a more consistent cushioning performance over the course of a marathon, maintaining its effectiveness even late into the race. The Adios Pro 4, with its higher drop and slightly firmer midsole feel, provides a bit more structure and guidance but feels less agile in comparison.
