Saucony Endorphin Elite 2: The Softest Foam you can Run in

In 2025, novel midsole experiences are few and far between—some would even say foams have stagnated since ZoomX was released in 2017.  Saucony’s IncrediRun in the Endorphin Elite 2, however, is truly groundbreaking, providing a ridiculously soft ride that somehow remains highly runnable.
