Saucony Endorphin Pro 4 vs Endorphin Pro 5

The Saucony Endorphin Pro 5 and Saucony Endorphin Pro 4 are two iterations of the same super shoe, but the newer version clearly doubles down on being an approachable, stable race option without losing its performance edge. The Endorphin Pro 5 sits slightly lower overall, including in the forefoot, and it pairs that with a slightly higher drop and a firmer forefoot feel that makes toe-off feel more controlled and consistent. Also, its cushioning holds up better as the miles add up, even if neither shoe is a standout for maintaining cushioning over very long distances. The Endorphin Pro 4, on the other hand, feels a touch more energetic underfoot and, with its higher stack, offers a bit less ground feel, which some runners might prefer.
