About the brand

Brooks has been singularly focused on the run since 1914, channeling more than a century of biomechanics research into shoes built to keep you moving. From nitrogen-infused DNA cushioning underfoot to the trail-ready Cascadia and road-smooth Ghost franchises, every pair is engineered around how real runners actually move. At Mountain Sports, we love Brooks because they do one thing exceptionally well — dependable, well-cushioned shoes that turn everyday miles into something you look forward to.

Questions, answered

Before you buy.

Pulled from chats, emails and store visits. The things people actually ask us before they buy. Don't see yours?

Ask a question
How do I find the right size?

Most runners take their usual running-shoe size in the Cascadia 20, with about a thumb's width of space ahead of the longest toe. It runs true to size — if you're between sizes or wear thicker socks, size up a half. Check the size guide on this page, and note the D (Regular) and 2E (Wide) width options.

Is the Cascadia 20 good for hiking?

Yes. The Vibram Megagrip outsole, protective toe cap, and stable TrailAdapt base make it a great choice for day hikes and fastpacking, not just trail running.

What changed from the Cascadia 19?

The 20 adds more cushion on a refined, supportive platform and, for the first time on a Cascadia, an all-terrain Vibram Megagrip outsole for grippier wet and dry traction.

Can I run roads in it too?

It's built for trail, but the cushioned ride easily handles road sections on the way to the trailhead. For mostly-road miles, a road shoe like the Brooks Ghost will feel smoother.
