What Our Gearhead(R) Experts Are Saying:"I've tested the Cascadia 19 GTX in soggy alpine meadows and rocky switchbacks, and its traction and waterproofing are unbeatable. The nitrogen-infused midsole makes it feel cushioned yet stable-ideal for all-day efforts on unpredictable terrain."When the mountain forecast promises rain, mud, and miles of trail, we lace up the Brooks Cascadia 19 GTX Trail Running Shoe and lean into the challenge. This trail workhorse blends comfort, protection, and support to tackle technical terrain in any condition. With a GORE-TEX(R) Invisible Fit membrane bonded directly to the upper, the Cascadia 19 GTX keeps feet dry without feeling stiff or bulky. We love how the new Trail Adapt System teams up with the Ballistic Rock Shield and nitrogen-infused DNA Loft v3 midsole to deliver a ride that's soft on impact, stable under pressure, and flexible across mixed trail surfaces. TrailTack Green rubber delivers all-surface grip and leans into sustainability with 25% recycled content. Whether you're skimming through puddles or scrambling steep ridgelines, this shoe keeps your stride secure, smooth, and steady.
