Your go-anywhere tank! Your updated Men's Brooks Cascadia 19 trail runner is built to tackle unpredictable mountain terrain with more cushion and more confidence - in other words, meet the most adaptable Cascadia yet. What's new? A big upgrade in nitrogen-infused DNA LOFT v3 cushioning (+2mm heel, +4mm forefoot), plus the newly enhanced Trail Adapt System that blends a Ballistic Rock Shield right into the midsole for smoother ground response. The protective air mesh upper hugs your foot with breathable structure, while the TrailTack Green outsole on your Cascadia 19 grips wet rocks like a champ.
