Work your way to the top of the local skate racing scene in the Alpina RSK Skate Boot. This high-performance boot borrows features from Alpina's elite-level racing boots, but uses a plastic--rather than carbon--cuff and heel counter for a little bit of cost savings. The solid cuff and heel counter, together with a stiff flex, efficiently transfer power to the ski, so you can go for serious results, and the ventilating lining and footbed keep you fresh during long, hard training days. The boot aligns your foot with a gentle downward slope toward the heel for better balance and stability, so you'll be able to step through corners comfortably and kick harder and more efficiently. Fine-tune the lace closure and adjust the power strap for a comfortable, supportive fit, and dial in the perfect amount of rear-foot retention with the Alpina's heel grip regulator. Thinsulate insulation protects against frigid temps as you're zooming around the course, while allowing perspiration to escape so you avoid swampy feet. The one-piece overboot, waterproof zipper, and waterproof upper keep moisture from spraying or falling snow from seeping in and soaking your feet, so you'll be able to hammer courses and take your results up to the next level in comfort.
