The Saucony Endorphin Speed 5, designed as a lightweight trainer, features updates in the upper, midsole, and outsole compared to the Speed 4. Both versions utilize PWRRUN PB midsoles, providing medium-firm cushioning with standard stack heights. Key differences include the Speed 5’s single wing nylon plate, enhancing flexibility during runs but offering less stability than the dual-wing Speed 4. The Speed 5 is also noted for improved outsole durability due to increased rubber coverage, targeting heel strikers, while the Speed 4 maintains a quicker transition thanks to a more pronounced forefoot rocker.
The Speed 5 has a more flexible forefoot and better durability for heel strikers, but the Speed 4 provides more speed assistance and stability.
While both have the same stack heights and use PWRRUN PB midsoles, the Speed 5 has a new single wing design that impacts its ride character.
