Built using the experience gained from Madshus'' World Cup winning boots, the Hyper Race Performance Series utilizes RevoWrap upper technology, providing even pressure around the whole foot for a more secure fit. Despite being lightweight, the Hyper RP Series boots retain their reputation for comfort with the PU lower, MemBrain Softshell lace cover, and water-repellant zipper, keeping your feet warm and dry all season long.
