Saucony Endorphin Pro 4 First Run Review

The Saucony Endorphin Pro 4 is the latest update to a series of marathon racing shoes beloved by recreational runners. Its predecessor, the Pro 3, was fast, fun and forgiving all in one, helping me score my first ever 26.2 finish. The Endorphin Pro 4 makes slight tweaks to the formula and keeps the same price ($225), but it faces a much stiffer market than when the 3 was released in 2022. Here are my thoughts on the Pro 4 after a 20 mile double day. 0:00 - Intro 3:23 - Overview 4:03 - Competitors 14:54 - Fit & Feel 21:05 - Morning Run 29:45 - Post-Run Thoughts 37:47 - Comparisons 40:17 - Afternoon Run 43:33 - Thoughts after 20 Miles 50:49 - Durometer Test
