About This World Cup–Level Power Strap for Expert Skiers: The Booster Strap World Cup model is the firmest, most aggressive ski boot power strap available—built for racers and expert skiers demanding maximum responsiveness, energy transfer, and control on steep terrain and icy courses. High-Strength Elastic for Maximum Precision & Flex: Unlike standard Velcro ski boot straps, this elastic expert booster strap eliminates cuff gap, locks your shin into the boot tongue, and gives you explosive rebound, quicker edge transitions, and improved ski precision at high speed. Installation Hardware Included for Easy Mounting: Every Booster Strap WC package includes complete install hardware, making it simple to replace old ski boot tightening straps, ski boot top straps, or worn-out OEM power straps. Works with most downhill ski boots, SkiMetrix, GripWalk, and performance racing boots. Superior Shock Absorption & Shin Protection: The elastic design absorbs vibration, tackling “shin bang” and impacts from rough snow, gates, freeride hits, or aggressive carving. Pairs perfectly with boot gloves, insulated boot covers, boot liners, cat tracks, and other boot-comfort accessories. Trusted by Olympic Racers & High-Performance Skiers: The official choice for elite athletes using Booster Dynamic Power Straps and Expert Booster Strap systems. Ideal for upgrading ski boot power strap replacements, ski tuning setups, ski carriers, boot transport gear, and high-performance skiing equipment. Overview Care instructions : Machine Wash
