The FXR Youth Boost Boot is a premium winter snowmobile boot built for young riders who demand maximum warmth, waterproofing, and all-day comfort in extreme cold. Stepping up from the Octane, the Boost adds FXR's HydrX™ waterproof membrane and a removable liner for versatility, while pushing the temperature rating to -40°C. Dual hook-and-loop adjustment straps plus a drawstring and toggle upper cuff deliver a precise, secure fit across a wide range of youth sizes. The concave TPR outsole provides reliable traction, stable footing, and better snow floatation, while the toe kick makes it easy to clear snow and ice.
