Snappy with a rocker that comes alive at pace, but the narrow fit causes toe pressure for several.

PositiveGabrielle Hondorp, despite disliking past Endorphins, found it light, comfortable and gentle on her shin-splint-prone legs. She notes a large arch gap and thin tread that may wear quickly.

PositiveFirst 10 miles in the Endorphin Speed 4: comfortable secure upper, soft foam with good energy return, stable, grippy and light.

Positive60+ miles covered, from easy runs to intervals and long efforts, including wet roads. They liked the secure, true-to-size fit with less heel rub than the previous version, the lively cushioned ride and improved wet grip. They found the knitted tongue and lace tabs flimsy, noticed some wobble when running sloppily, and one heel striker wanted more forefoot cushioning on long fast runs. A versatile do-it-all trainer.
