NegativeAbout 250 miles over several months, from a heavier runner (around 220 lb). Step-in feel and lockdown are good with no heel slip, and the outsole wears very well. But the ride felt flat from the start, like running on cardboard at higher speeds, with little energy return and little fun. They kept reaching for other shoes and did not think it was good value at around $169.
Runners describe the Endorphin Speed 5 as a firm, stable and light shoe that works for tempo and speed sessions, and some use it for everything. Reactions are lukewarm, with several calling it flat, dull or harsh, and firmness is the most common note. A few get heel slip or chafing.
