LACING: BoaA(R) Closure System Powered - A Burton-exclusive upgrade to BoaA(R), Lockdown Lacing increases heel hold by integrating three distinct lacing zones with a single crank-able dial.

Available in both BoaA(R) dual zone and single zone systems. LINER: Youth Imprint(TM) Liner CUSHIONING: DynoLITE Outsole - Superior cushioning, improved board feel, and consistent support in a 20% lighter weight construction.

COMFORT: Snow-Proof Internal Gusset - All Burton boot tongues feature an internal gusset construction to completely seal the lower zone of the boot, keeping feet warm and dry.
