Saucony Endorphin Speed 2

The Saucony Endorphin Speed 2 arrives later in June. Saucony designed the original Endorphin Speed as a quick shoe for tempo days — ideal for speed workouts. It has a nylon plate that uses Saucony’s Speed Roll geometry to quickly move through your gait cycle. The plate was designed to propel you forward. Runners quickly discovered the versatility of the original Endorphin Speed and began using it for everything from daily training to racing. The plate is more flexible and more forgiving than the carbon plate in the Endorphin Pro. The update — version 2 — makes very small tweaks to the original model. The upper mesh has a few more perforations for better breathability and the heel has some additional structure. Like the original version, this shoe “just works.” If you liked the first version of the Endorphin Speed the update will not disappoint.
