The complete Saucony Endorphin Speed lineage
The Endorphin Speed is Saucony's nylon-plated tempo trainer, the shoe that made the super trainer a category when it paired race-day PWRRUN PB foam with a flexible plate at $160 in 2020. Its history since is a tug of war over what it should be: the 3 widened the platform and steadied it (the great schism of the fan base), the 4 firmed it up, the 5 walked that back to broad applause, and the 6 (June 2026) is the first true platform change, with new PWRRUN PBX foam on 3 mm more stack. This page tracks every version.

- What is the newest Saucony Endorphin Speed?
- The Saucony Endorphin Speed 6, released in 2026. List price at launch was $175.
- Which Saucony Endorphin Speed versions are hard to find now?
- Endorphin Speed 1, Endorphin Speed 2. They are discontinued at retail, so Amazon carries whatever stock remains and sizes disappear one by one.
- Which Saucony Endorphin Speed should I buy?
- New to the line: buy the Endorphin Speed 6. Loyal to the older ride: the previous version rides differently from the current one, and remaining old stock is the only way to get it. See the what-replaced page for that version before deciding.
