Trail runners have three key requirements from their shoes--traction, rock protection, and support--and the Brooks Cascadia delivers on all three. The rugged TrailTack outsole has deep lugs made from sticky rubber for tons of grip. The integrated rock plate smooths out impacts on uneven terrain. And the cushioned, high-tech BioMoGo midsole offers excellent arch support for mile after mile of singletrack. If you're looking for a do-it-all trail runner that's ready for any High Sierra adventure you can trow at it, the Cascadia 15 is the shoe for you.
