Saucony will release the Endorphin Speed 6 on 15 October 2026, priced at $175, bringing a new midsole foam and a reworked plate to one of the best-known fast daily trainers on the market. The sixth version of the shoe is built around the brand's PWRRUN PBX foam, a PEBA-based compound, and a redesigned nylon plate that is intended to keep the shoe lively without the stiffness of a carbon unit.
The Speed has long occupied the space between a daily trainer and a race-day shoe, and the update is aimed at runners who want one pair for tempo sessions, long runs and, for many, race day itself. Retail listings place the shoe at a stack of roughly 38mm in the heel and 30mm in the forefoot with an 8mm drop, although runners should check final specifications against the brand's own product page once the shoe goes on sale.
The launch sits comfortably within a wider autumn trend. Nike's Alphafly 4 has already moved into production, and brands across the category are leaning on PEBA-based foams to deliver energy return at prices below those of the elite racing models. At $175 the Endorphin Speed 6 is positioned beneath those premium options, and it will be compared directly with the supershoes now being worn by club runners.
The nylon plate is the key talking point. Saucony has used the material across the Speed range for several generations, arguing that it offers a smoother, more forgiving transition than carbon, and the plate has been redesigned for this release. How that translates on the road will only become clear as independent reviews appear after launch, and early impressions from retailers should be treated with caution.
For UK readers, pricing and availability will be confirmed closer to launch. Runners considering the shoe for a spring marathon block will want to see how the PBX foam holds up over high mileage, since durability has been a recurring question for lighter PEBA-based foams. Running Lookout will review the shoe once pairs are available.
