Saucony Endorphin Speed 5

Saucony Endorphin Speed 5 review: what runners say

Fit

True to size with a slightly wider toebox than the previous model. Runners with wide or high-volume feet should consider going up a half size.

Feel

PWRRUN PB delivers balanced cushioning and a responsive feel without the propulsion of a carbon plate. The single-wing nylon plate increases torsional flex compared to the v4, making the ride softer and less propulsive.

Durability

Outsole reinforced at the lateral heel. Estimated lifespan 500–600 km for runners under 165 lb. No significant wear detected after 92 km of testing.

Best for

Tempo runs, long repeats, and races up to the half marathon for runners at roughly 6:26/mi 10K pace. Workable for easy runs; less suited for long runs beyond 18–19 miles.

Weak points

Multiple sources report the v5 is less responsive and propulsive than the v4 due to the redesigned plate. The $175–200 price point is considered steep for a shoe with no substantial updates.
