Endorphin Speed 5

$175.00Super Trainer

The Saucony Endorphin Speed 5 is presented as a highly versatile "super trainer," evolving its proven design with a full-length PWRRUN PB foam midsole and a flexible nylon plate to deliver an energetic, bouncy, and responsive ride with subtle stability. It excels across a broad spectrum of runs, from daily training and tempo workouts to intervals and longer races, making it an excellent all-rounder for runners seeking performance without a carbon plate. Its breathable upper offers a secure and comfortable fit with improved forefoot space, although the tongue design is sometimes noted as unconventional and some find it less ideal for exceptionally wide feet. While the updated outsole generally enhances durability, some reviewers experienced the foam firming up or outsole wear after significant mileage, and its premium price is a common point of discussion.

Considerations

PWRRUN PB foam firms up and loses initial bounce after roughly 80 miles
Outsole durability concerns, including exposed foam wear and occasional peeling
Ride may feel too firm or less cushioned for runners preferring maximal softness
Midfoot and heel fit may feel snug for wider feet
Tongue design is short and unconventional
