The Mesa Trail II gets even better with stronger, more durable and protective welded components on the upper, breathable mesh and a moisture-wicking lining, ready to go with you wherever you go. LIGHT COMFORT You'll love hitting the trails with this perfect balance of lightweight comfort and safety. At just 221 g in size 42, the Mesa Trail II is even lighter than the original. Adjustable midfoot and instep straps adapt perfectly to your foot. The thin, durable toe cap and tough sidewall weld work hard to give you extra protection. TRAIL-GRIPPING Our patented FeelTrue sole features 3.5 mm studs for optimal traction. Enjoy the way our 3.5 mm TrailFoam layer evens out bumps during your trail run. If your feet don't feel as good at the end of the day as they did at the beginning, you haven't tried Mesa Trail II. Life-changing comfort and superior performance are achieved by letting your feet do what comes naturally - bend, move, flex and feel. All Xero Shoes feature a wider, foot-shaped toe box that allows your toes to spread and relax, a "zero drop" non-raised heel for correct posture, a ground-flush design for better balance and agility, and a flexible sole that gives you the combination of grip, protection and ground feel your brain craves to help you live life feet-up premier.
