Saucony Endorphin Trainer

Saucony Endorphin Trainer review: what runners say

Fit

True to size for most runners. The internal volume is generous: those with narrow or slim feet may find too much room.

Feel

The top IncrediRun layer is soft and responsive on initial contact; the dense PWRRUN bottom layer tends to dampen that response after a few miles, feeling heavy and lifeless. Some runners appreciate the combination on easy long runs; others find it inconsistent.

Durability

Partial rubber coverage on the lateral heel and medial toe-off zone; the rest is exposed carbon rubber EVA. Reduced traction on wet surfaces. Exact mileage data not captured by sources.

Best for

Runners looking for a high-cushion, stable long slow distance trainer. Suited to forefoot and midfoot strikers. Not recommended as an uptempo shoe despite the brand's stated positioning.

Weak points

The dense, unresponsive bottom PWRRUN foam neutralizes the IncrediRun layer's contribution. High weight (approx. 303–310 g in US size 10) is out of class compared to competing super trainers. Flat ribbon laces noted as uncomfortable by multiple sources. Insufficient outsole coverage.
