The Irish Setter Rutmaster RPM Hunting Boot boasts patent-pending ExoFlex technology, which expands to accommodate the back of your foot. Once you're in, it contracts for a lock-tight, high-performance fit, for the best-fitting, easiest on-and-off rubber boots you'll ever own. Printed in a vibrant Realtree Xtra camouflage pattern, the waterproof and scentproof upper is made from RPM composite materials for stability, strength, and comfort without all the excess weight. The airmesh lining lets air circulate throughout the boot, ensuring that feet stay comfortably dry. A ScentBan treatment in the lining helps control odors by killing odor-causing bacteria, keeping feet fresher longer. The removable EVA footbed provides ample support where you need it most. The Mud Claw RPM outsole's unique tread design and aggressive lug pattern release mud and dirt for superb stability and traction on even the toughest terrains. The boot's pull-on design allows for quick, easy on and off. 17" shaft height. Weight: 3 lbs. 2 oz. Medium width. Imported.
