The Saucony Endorphin Speed series is widely regarded as a top-tier, versatile performance daily trainer that excels at speedwork while remaining comfortable enough for daily miles. The Speed 4 and 5 are highly similar in performance, meaning if you can find the Speed 4 on sale, it offers exceptional value. While generally loved for its responsiveness and energy return, some runners may find the ride firmer than ultra-soft maximalist shoes or notice less traction on non-flat surfaces.
