The US Military is a force to be reckoned with, and the Danner Reckoning Boot forges ahead with that same spirit and determination. It's a true-blue Combat Boot built for the complex, ever-shifting modern battlefield, with premium GORE-TEX lining and all the best components to keep you on your toes. The waterproof/breathable GORE-TEX lining keeps water out while allowing vapor inside to escape-so you stay cool, calm and collected in the heat of battle. And 400 gram Thinsulate Ultra Insulation provides an added measure of warmth for cold-weather operations. The Reckoning is built on Danner's 851 last to be athletic and supportive while providing extra room in the toe, and features the Danner Vibram All-Terrain (DAT) platform: a combination of Vibram midsole and outsole compounds calibrated for maximum shock absorption and comfort. The rubber outsole delivers high-mileage durability along with multi-directional traction that grabs and holds at all angles and on all surfaces. In short, the Danner Reckoning is lightweight, comfortable, streamlined and configurable to fit any theater or uniform. It's USA made, Berry compliant, and approved for uniform wear. 100% waterproof/breathable GORE-TEX lining keeps water out while allowing sweat to escape 400-gram Thinsulate Ultra Insulation Suede and abrasion-resistant nylon upper provides durability without excess weight Built on the Danner 851 last for an athletic, supportive fit with extra room in the toe Danner Vibram All-Terrain (DAT) platform: both the midsole and outsole are made from premium Vibram materials for max shock absorption and comfort Vibram All-Terrain rubber outsole features omni-directional lugs for traction at every angle and on all surfaces Double-bevel tread pattern helps reduce debris from collecting in the outsole Removable open-cell polyurethane footbed for comfort Double rivet speed lacer for secure heel lock Safe-to-fly certification Meets US Army AR 670-1 requirements for option
