Description

Adapt to the wild in the stabilizing, trail-ready Cascadia 20. For its 20th edition, Brooks' most rugged everyday trail shoe gets a major platform update — more cushion underfoot on a refined, supportive base that keeps you planted on technical and rugged terrain. Responsive, nitrogen-infused DNA FLASH v2 cushioning gives you an energetic push-off mile after mile, while TrailAdapt Technology delivers a wide base of support and adaptive lugs that move with the ground beneath you. For the first time on a Cascadia, an all-terrain Vibram Megagrip outsole brings confidence-inspiring traction on wet and dry surfaces.

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.
