Altra Olympus 6 Sizing Guide: Does It Run Small or True to Size?

Fit Notes

Altra Lone Peak 9+

The Lone Peak runs true to slightly long, while the Olympus 6 runs short. Go a half size up from your Lone Peak size. The Olympus also feels a bit lower in toe-box height and much taller underfoot, so expect a more cushioned, less ground-connected ride.

Hoka Speedgoat 6

Both are max-cushion trail shoes, but the Speedgoat has a 5mm drop, a narrower toe box, and a lighter, rockered ride. The Olympus gives your toes much more room and sits flat. Size up a half from your Speedgoat size for length; width will feel far more generous.

Brooks Caldera 8

The Caldera is a softer, more forgiving max-cushion trail shoe with a 6mm drop and a medium-width forefoot. The Olympus is firmer, flatter, and roomier up front. A half size up keeps your toes clear of the bumper on long descents.

Altra Olympus 5

The Olympus 6 feels a little snugger through the forefoot and much more secure in the heel than version 5. If your Olympus 5 already felt snug in length, go up a half. If it felt roomy, your same size may work, especially in the wide version.

Altra Torin 8

The Torin 8 runs true to size with a snugger midfoot. The Olympus 6 runs short but feels roomier up front. Size up a half from your Torin size for the Olympus, and expect a much taller, stiffer, heavier shoe.
