Our Verdict

adidas Adizero Evo SL

Saucony Endorphin Speed 5

The adidas Adizero Evo SL and Saucony Endorphin Speed 5 both deliver a lively, modern bounce underfoot, but they suit slightly different runners. The adidas is an unplated uptempo trainer that feels lighter on foot and maintains more consistent cushioning as runs get longer, with a midsole that absorbs impact well while still returning energy efficiently. The Saucony is a plated super trainer that feels more structured and inherently more stable, but slightly less cushioned overall. While neither shoe is truly plush, the adidas feels a touch more forgiving over extended efforts, whereas the Saucony leans into its plate-driven snap and guidance.
