Endorphin Speed 4

On a third pair and loves it, but each lasts only 300–325 miles.

“I’m on my third pair of the Speed 4s (and sad that I can’t seem to find my size anymore) I love the shoe but can’t get more than 300-325miles per pair”

A disappointment: heavy and needs more effort than the Speed 3.

“the 4 was such a disappointment. The 3 was so springy whereas the 4 felt heavy and required lot more effort for pace.”

Uses it for intervals and 5k/10k races; normal at easy paces and turns over really well when fast.
