The Mesa Trail WP is a fully waterproof update to our best-selling trail running shoe. You'll stay dry with the Mesa Trail WP's gusseted tongue, seam-sealed inner booty, and proprietary Xero-Tex™ waterproof membrane. Lugged soles and our iconic adjustable midfoot and instep straps keep you secure and stable during off-road adventures. Like all Xero Shoes, the Mesa Trail WP is lightweight (9.6oz/272g M9) and lets you save your energy for exploring new trails.
