The Salomon Men's Utility Pro TS CSWP Boots don't mess around when it comes to keeping your feet warm. The best way to make sure something gets done right is to do it twice, so Salomon doubled up on the features of the Utility Pros, so you won't have to worry if its too cold or wet for these boots.Like any good winter boots, the Utility Pros are well insulated with Thinsulate insulation and are lined with synthetic fur for an extra dose of warmth. Protection from moisture is two fold with both a waterproof nubuck leather making up the bulk of the upper and Salomon's Climashield waterproof membrane behind that to ensure a waterproof barrier between your feet and the wet winter weather. Since an uncomfortable boot is pretty much worthless, Salomon went ahead and threw in all the bells and whistles to ensure these boots are about as comfortable as your favorite pair of slippers. A soft plush lining, cushioned EVA midsole, and a die cut Ortholite insole all come together to keep your feet comfy, cushioned and cozy from the moment you put them on until it's time to take them off.
