Questions runners ask
- Which is lighter, the Saucony Endorphin Speed 3 or the Endorphin Speed 4?
- Neither by a meaningful margin. Both weigh about 8.1 oz in a men's US 9.
- Do the Saucony Endorphin Speed 3 and Endorphin Speed 4 come in the same widths?
- Yes. Both run in D for men's sizes, so a width that fit in the Endorphin Speed 3 carries over to the Endorphin Speed 4.
- How do the stack heights compare?
- 36 mm heel and 28 mm forefoot on the Saucony Endorphin Speed 3, against 36 mm and 28 mm on the Endorphin Speed 4. Same platform under both.
- Is the Endorphin Speed 4 still the newest Endorphin Speed?
- No. The Endorphin Speed 5 replaced it in 2025, so the Endorphin Speed 4 now sells as an older model and usually below its $170 list price.
