Like the original version, runners will want to strap in for this speedy ride time and time again. The SPEEDROLL midsole design is efficient and will help runners more easily sustain their speed throughout their run. The PWRRUN PB foam feels soft underfoot, but it also packs a serious punch in terms of energy return and will propel the wearer through every stride.

With Speed in the name, you better produce a fast shoe, and the Endorphin Speed 2 once again delivers.

Overall, the Speed 2 is another excellent shoe that is sure to be a favorite among runners throughout 2021 for fast training runs or everyday workout needs. Understandably, colorway preferences are subjective, and some runners may love rocking the 'racing' print, but it is an interesting style choice nonetheless. The only small negative our team could find while testing the Endorphin Speed 2 was the 'Reverie' colorway. Additionally, your feet will have no problem staying cool thanks to the more breathable design. The newly updated FORMFIT mesh upper is snug throughout, offering a more secure lockdown when pushing faster paces. The strategically placed carbon rubber outsole remains impressively durable and offers no-nonsense traction to keep your footing on the roads. The PWRRUN PB, nylon plate, and SPEEDROLL midsole offer a fast and efficient ride that has the versatility to excel during a variety of runs. Saucony responded to this success by reintroducing the same midsole and outsole combination that everyone loved in the original Speed but adding a refined upper design. The original Endorphin Speed was one of the biggest successes of 2020, making the Running Warehouse 'Most Versatile Shoes' list and gaining praise throughout the running community for its fast and versatile ride.
