The Rutmaster 2.0 Insulated Rubber Hunting Boot boasts Irish Setter's exclusive ExoFlex technology, which expands to accommodate the back of your foot. Once you're in, it contracts for a lock-tight, high-performance fit that provides toe spring and agility in every stride. Breakthrough RPM composite technology significantly reduces the weight of the boot for stability, strength, and comfort – without all the extra weight. The waterproof, vulcanized rubber and 3.5mm neoprene upper is printed in a Realtree Xtra camouflage pattern for maximum stealth in the field. A ScentBan treatment in the lining helps control odors by killing odor-causing bacteria, so feet stay fresher longer. The boot is packed with an astounding 1,200 grams of PrimaLoft Gold Eco insulation – featuring 90% post-consumer recycled fibers made from plastic bottles – providing exceptional warmth in both wet and dry conditions. Cement construction provides maximum flexibility and comfort, while the removable polyurethane footbed offers ample cushioning underfoot. The injected nylon shank adds extra support where you need it most. The Mud Claw RPM II composite/rubber outsole features a unique tread design which releases mud and dirt, and its aggressive deep lug pattern yields superior traction and stability on even the toughest terrains. The pull-on design allows for easy on and off, and the adjustable side strap cinches up easily for a customized fit. The boot is built around a precision-made last that's specifically designed to address the nuances of a woman's foot shape for improved fit and performance. 15" shaft height. Weight: 4 lbs. 6 oz.
