Deckers X Lab is the innovation lab behind Hoka (the cushion king) and Ugg (the comfort queen). Deckers is the parent company of both those brands, as well as Teva and Sanuk. This is a waterproof boot, as denoted by the GTX in the name. A Gore-Tex waterproof membrane ensures dryness through any activity. The Eco-Tan suede upper keeps the foot warm while providing a perfect fit thanks to the ten eyelets with hiking laces and lace covers. The midsole features a supercritical EVA midsole frame wrapped around an ultra-lightweight and high rebound nitrogen-infused TPX-Ponent midsole core. In true Deckers X Lab fashion, they layer-cake the comfort with an additional supercritical E-TPEE sock liner. It also has a rocker geometry that rolls you through every step. Theres also a dual forked, V-shaped carbon fiber plate sandwiched in the midsole which facilitates rolling forward in connection with the front rocker. Underneath the foot is a Vibram Litebase outsole This boot is incredibly comfortable. It fits perfectly, it keeps the feet warm and dry, and best of all it looks absolutely amazing.
