Questions runners ask
- Can I go straight from the Saucony Endorphin Speed 1 to the Endorphin Speed 3 and skip the Endorphin Speed 2?
- Yes, but going Endorphin Speed 1 to Endorphin Speed 3 means taking one change in a single step: the Endorphin Speed 3 is where the ride moved. Drop holds at 8 mm, so the difference is foam and fit rather than geometry: PWRRUN PB foam (expanded-bead PEBA) to PWRRUN PB foam (expanded-bead PEBA).
- How much did the weight change across these two updates?
- 0.3 oz on in total, 7.8 oz to 8.1 oz in a men's US 9. Almost all of it came in the second update; the Endorphin Speed 2 weighed 7.8 oz.
- Is the Endorphin Speed 2 the better buy than either of these?
- On paper it splits them: 7.8 oz against 7.8 oz for the Endorphin Speed 1 and 8.1 oz for the Endorphin Speed 3, on a 35.5 mm heel and a $160 list price. Availability decides it: Amazon's Endorphin Speed 2 stock is gone in both men's and women's sizes, so it is not a live option.
- Where does the Endorphin Speed 3 sit in the Endorphin Speed lineup now?
- Two versions on from the Endorphin Speed 1, and already replaced itself: the Endorphin Speed 4 arrived in 2024. If you are shopping old stock anyway, price the Endorphin Speed 3 against it before deciding.
