What Our Gearhead(R) Experts Are Saying:"This version of the Cloudsurfer Trail 2 WP is my go-to for rainy trail runs or stream-laced routes. The waterproof membrane really holds up, and the Missongrip(TM) outsole has tackled everything from muddy switchbacks to rocky scrambles without missing a beat. My feet stay dry, supported, and comfortable through every mile."When the forecast shifts but the call of the trail doesn't fade, we reach for the Cloudsurfer Trail 2 WP Running Shoe from On.
