The Hyper RPS Export has a full-length composite lastboard, high cuff, and R3 outsole for extra performance kick on race day. Designed for Race Performance Nordic skate ski boot, the RPS is still known for comfort with a MemBrain® Softshell upper, and RevoWrap™ technology that creates a more secure fit all the way around the whole foot, with great water repellency while staying breathable. RevoWrap™ construction envelops the foot with a single piece upper, from the heel around the toe and back to the heel and from the outsole up to the lacing on the eyestay. The upper materials conform to the foot with minimal seams, providing even pressure distribution. As you tighten your laces, it pulls directly on the upper material connected to the outsole, which help delivers a snugger, more comfortable fit, leading to precise control of your skis. The Hyper RPS Export boots feature MemBrain® softshell lace covers. This waterproof and breathable material helps keep the foot warm, dry, and comfortable and are totally PVC-Free.
