Zamberlan Exotrail GTX Shoes - Women'sGrey/Sky9. The Exotrails secret sauce is its PU exo-skeleton which provides more structure and support than a trail runner especially in uneven terrain and when carrying heavier loads. In between the exoskeleton a fully breathable mesh upper is fused to a seamless GORE-TEX ePE Invisible Fit membrane for a natural comfortable fit. For rough rocky terrain the Exotrail uses a real rubber toe rand with PU backing in the toebox for true hiking protection. The Vibram Bayu Megagrip outsole features full-coverage self-cleaning Helix lugs for highly responsive grip on unpredictable terrain. The midsole uses a greater density EVA for cushioning and durability like our hiking boot. The Exotrail gives the foot room to spread naturally inside the shoe with a last designed for comfort and long days on the trail. Whether you seek speed long distance or both the Exotrail outperforms trail runners for more durable performance protection and comfort on any terrain.
