K2 Sidecar Youth Snowboard Boots 2027

The K2 Sidecar is a warm, supportive youth snowboard boot with an easy-to-use BOA® closure and a fit system designed to keep young riders comfortable as they progress.

Built for young riders who are spending more time on the hill, the Sidecar combines easy entry with dependable all-day comfort. The Youth BOA® Fit System uses a simple dial closure and TX3 textile lace to create a secure, even fit across the boot without the fuss of traditional laces. Its Flex Zone Upper supports a smooth, natural forward flex, helping riders move comfortably while learning turns, linking lines and taking on new terrain. Inside, the heat-mouldable Comfort EVA liner brings warm, breathable cushioning, while internal J-bars help hold the heel and ankle in place. The Grows-A-Long shim system lets you adjust internal volume as feet grow, extending the useful life of the boot.
