THE SHORT ANSWER
The Endorphin Speed 6 replaces the Speed 5, but it does not reach retail until October 15, 2026, at the same $175 list price at launch. It moves to new PWRRUN PBX foam on 3 mm more stack with a redesigned nylon plate, the first real platform change in the line. Until the 6 lands, the Speed 5 is the version you can actually buy, and retailers were still clearing it as of September 2026.

Stay on your shoe, or switch?
Changed characterOn paper, the biggest update the line has had: new PWRRUN PBX foam, 3 mm more stack at both ends, a redesigned plate, and 0.6 oz less weight, at the same $175. In practice, unproven. As of late July 2026 the major review outlets had not published, and the one early review out praised a consistent, energetic ride between daily trainer and racer. Treat the spec sheet as the promise, not the verdict.
Stick with the Endorphin Speed 5 if
- You want a proven ride; the 5 is discounted and widely stocked
- You would rather read the reviews before betting on a new foam
- The 5's lower stack and firmer feel suit your form
Move to the Endorphin Speed 6 if
- You want the taller, lighter platform now
- The 5 never felt cushioned enough on long sessions
- You are fine being early, and Amazon stock has caught up
What loyalists said about the update
Too new to call. The shoe reached partner retailers on June 18, 2026, ahead of Saucony's own site, and no meaningful community consensus existed six weeks later. If the PBX foam runs the way it specs, the 5-to-6 handoff will be the line's most substantial upgrade; if not, the 5 is discounted, proven, and everywhere.
