Saucony Endorphin Pro 4 Reviews

Ran two 2-mile races in the Endorphin Pro 4 and it made them feel fast, but a 7-mile interval session in it made their knees hurt.

Loves the Endorphin Pro 4 more than the Alphafly 3 and has raced both an Ironman and an Olympic-distance triathlon in it.

Ran the Chicago marathon in the Endorphin Pro 4, their first carbon marathon; perfect, with a 12-minute PB.

A really nice update with an improved upper and midsole that brings back the propulsive feel. One tester compares it to the NB SC Elite v4, one of her favourite racers.

Fit is truer to size than earlier versions. It excels over longer efforts. One tester finds it very firm: great for 5K/10K, but she wouldn't run a marathon in it because it lacks compliance. Little wear at 30 miles.

A stable, controllable first super shoe with great traction, propulsive but understated. It falls short of rivals on outright bounce and versatility. A stiff overlay caused a pinky-toe blister on the first 10-miler.

His planned marathon race shoe: smooth, semi-soft and bouncy, and great for 10K-to-marathon pace for mid-range (3:15) marathoners. About half an ounce heavier than v3, with a numb, disconnected ground feel. Probably not ideal for sub-3 runners.

A 39-minute 10k runner feels a considerable plate boost in the Endorphin Pro 4 and ran a 3:10 marathon in them.

At 6'1 and 190lb, the Endorphin Pro 4 feels like speed hacks when pushed; intervals end up faster than targeted.

Set a half-marathon best in it and recommends it as a good first plated shoe.
