Built for extreme warmth plus hunting boot comfort, the Predator Extreme is ready for everything from late-season hunts to snowmobiling adventures to ice fishing in sub-zero conditions. Constructed from the inside out with the key focus on warmth and comfort in brutally cold environments, the boot boasts a removable 9mm Texel® liner that warms your feet and draws moisture away from the surface of the skin. This liner also sports our exclusive heat pack pocket under the toe area for the coldest temperatures. And, for even more insulation, the boot is outfitted with a layer of 1,200-gram Thinsulate™ Ultra insulation for optimum heat retention. The moisture-wicking liner and removable Moisture Trap footbed work in unison to draw perspiration away from the skin, so your foot stays dry and warm. At the end of the day, simply pull both out and let them dry overnight. Thanks to our exclusive Dry-Plus™ barrier, these boots also deliver 100% waterproof performance. For the ultimate abrasion resistance, the exterior is crafted with a full-grain leather shaft and polyurethane molded shell panels. Non-glare, dimpled PU panels. Matte-finished EVA midsole soaks up ground shock. Roller-bearing and hook lacing system. Order the next larger size if you wear a half size. Order next size up if wearing with heavy socks.
