adidas Adizero Boston 13 vs Saucony Endorphin Speed 5

The Saucony Endorphin Speed 5 and the adidas Adizero Boston 13 are both plated speed trainers designed for uptempo efforts, but they differ notably in execution. The Saucony uses a softer PWRRUN PB foam paired with a nylon plate, resulting in a slightly more protective ride that allows you to do faster work. The Saucony is lightweight, flexible, and more accessible for runners who want plated performance without the rigidity of carbon. The adidas shoe, on the other hand, features adidas' carbon ENERGYRODS embedded in a firmer dual-density midsole, delivering a snappier, more aggressive feel. It's a shoe that rewards precise mechanics at faster paces, especially for runners who prefer a grounded, firm platform and don't mind a little stiffness underfoot.
