The Step On® Snowboard Boot for the next generationThe Burton Zipline Boa is a kid-tested, parent-approved winner for maximum fun and fuss-free function, with a softer flex and all-around easy Boa® closure. With the same performance and features like in the adult boots to get kids ahead, from the customized fit and warmth of a heat-mouldable Imprint™ liner to the weightless feel and heat-reflecting sleeping bag-foil. Add the easy entry/exit and mitt-friendly adjustability of the Boa® Closure system, as well as the easy-to-use Burton Step On® system, and you get a boot that kids want to wear all day. Outer Boot A soft flexing outsole and upper shell materials ensure fast learning. All Burton boot tongues feature a snow-proof internal gusset construction to completely seal the lower zone of the boot, keeping feet warm and dry. The Step On® Backstay is optimized for Burton’s Step On® system and is snugging up the fit between boot and highback. The rubber print backstays also shave weight and enhance material-to-material grip. The result of this printed rubber application is a more direct transfer from boot to binding to board for reduced rider fatigue. EST® goes beyond bindings by optimizing the soles on select boots for a more direct connection. Lower-profile, lighter weight, and with a reduced ramp angle, the Step On® EST® Outsole lowers your center of gravity and improves your feel. Liner The Youth Imprint™ Liner has integrated liner lacing and inner lace hooks to keep the feet in place no matter what. Heat mouldable with fit panels to ensure a perfect fit and completed with a Level 1 EVA Footbed for additional support and vibration absorption. Lacing System All Burton boots with Boa® have the virtually indestructible, Warrantied for Life performance of Burton-exclusive New England Rope laces. Built with a redesigned inner Coiler spool to route the laces, the dial-it-in system retains its quick, easy, and effective lace adjustment.
