PositiveA 225 lb runner loved the Endorphin Speed 4 over 200 miles and used it as a one-shoe rotation from easy runs to threshold, despite a snug midfoot.

Snappy with a rocker that comes alive at pace, but the narrow fit causes toe pressure for several.

PositiveUses the Endorphin Speed 4 mostly for long runs as a comfortable all-rounder, though not especially speedy for them; very durable, still perfectly good past 1,000 km.

PositiveNick Harris-Fry calls it an exceptionally versatile shoe for training and racing. Some runners may want a softer ride with more forefoot foam on long, hard runs.

PositiveA faster, more aggressive Speed and a go-to long-run shoe, much more durable than v3 for him. Excellent wet traction. The heel feels clunky at first, and calves work harder at speed.
