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

NegativeThe Endorphin Speed 4's toe box is far too narrow and tapered for their wider-than-average feet.

NegativeWants to love the Endorphin Speed 4 but it doesn't fit: even their regular size was too narrow, as was the Speed 3 half a size up.

MixedAfter 75 miles the Endorphin Speed 4 is fun and fast but too narrow; looking for Speed 2s.

PositiveFirst 5k in the Endorphin Speed 4 after a worn Invincible 3: much more playful and fun, about a minute per mile faster at a sustainable effort, though the forefoot is a little narrow and the exposed outsole foam is a durability worry.

NegativeGot the Endorphin Speed 4 in their usual US 9.5; the length is right but it is so narrow that it is a dealbreaker for them.

MixedThey say the midsole of the Endorphin Speed 4 feels much like the 3, but the toebox is very narrow and shallow and they had to go down a full size in the womens fit.

NegativeWith a narrow foot, gets circulation issues in the small toe after 5km in every run in the Endorphin Speed 4.

NegativeThe Endorphin Speed 4 was way too narrow, rubbing their pinky toe even sized up.

MixedAbout 100 miles in a week in them. They loved the light, breathable, secure upper and the bouncy, fresh-legged ride for steady daily miles and workouts, but found the toebox narrow (it aggravated an old friction spot), the heel flare awkward at recovery pace, and the cushioning going flat for a big, powerful runner on 2+ hour runs. Durability looked average to below, with the outsole worn through near 100 miles.

MixedOn a quick 3-mile treadmill test the Endorphin Speed 4 is firmer and snappier than the ES3, fantastic at faster paces but too hard at 10 min/mile, and the curved toe box caused pinky-toe numbness.
