Altra Olympus 275 Reviews

Took the Olympus 275 on an 8.6-mile hike with 1,900 ft of gain: very comfy, plenty of cushioning and protection, stable (more than their LP9) and grippy, though slab-like.

Just under 200 km, including a 139 km ultra with plenty of technical sections. They found it stable despite the tall stack, with a breathable upper, though summer heat is untested. The foam is on the firm side, so long stretches of hard pavement felt a bit unforgiving, and the grip would struggle in heavy mud. Best suited to trail ultras.

'Great shoe, terrible fit.' Light, stable and grippy, with good protection, but she couldn't get a locked-in fit. Her heels rubbed 5 miles into a run, and she got a blister on her second run. A thinner tongue than before, and stiff on pavement.

Vibram Megagrip performed on every surface, and the platform held him steady on the rocky Beluga 30K descents. Not a max-cushion fan, he's still more cautious in it on technical terrain. Zero drop needs easing into to avoid Achilles soreness. Verdict: 'Test It'.

A dependable max-cushion zero-drop trail shoe: outstanding grip in wet and mud, a secure, durable Matryx upper and surprising stability for 33 mm. No upper or lug wear after 100+ miles. Zero drop left his calves sore after long runs early on, so transition slowly.
