Our Verdict
Saucony Endorphin Speed 5
Saucony Endorphin Pro 5
The Saucony Endorphin Speed 5 and Saucony Endorphin Pro 5 bear the same family name, but they’re not quite in the same category. The Endorphin Pro 5 is the race-day super shoe, featuring a full carbon plate and a higher stack that make it feel more purpose-built for peak performance, and it comes in noticeably lighter to maximize efficiency. The Endorphin Speed 5 is the plated super trainer of the pair, sitting slightly lower and using a nylon plate instead of carbon, which adds flexibility and makes it more forgiving for everyday workouts.
