Best for: Runners wanting the Olympus cushioning platform in a lighter, more run-specific package

+1 earlier review from Run Moore

The more run-focused sibling to the Olympus 7, with one of the best performance-oriented uppers in the lineup and the same EGO Max midsole.

A surprising favorite from a reviewer who normally dislikes zero-drop shoes — the softer, lighter updated Ego Max midsole makes the Olympus 275 Hi-Lo comfortable, stable, and versatile across varied technical trail terrain, especially for long, easy-paced runs.

Best for: Long, comfortable trail runs and ultra-style training across varied technical terrain, especially for runners who want Altra's wide toe box without a harsh zero-drop ride
