A step up from hook-and-loop straps for rising riders who are ready for the micro-adjustable performance of the BOA Fit System. For the kid who's just learning to stand sideways or growing out of the hook-and-loop Mini-Grom boots, the Burton Grom BOA delivers comfort and a mellow flex that's great for learning on the bunny hill or stepping it up to the groomers. The BOA Fit System lets kids tighten or loosen their own boots without help from mom or dad. Our Room-to-Grow footbed gives the boots a full size of adjustment, so they can last more than one season. Open the door to a whole new world of mini-shred possibilities. LACING: BOA Fit System uses an inner spool to route the laces for a snug fit and easy lace adjustment with the simple twist of a dial. FLEX & RESPONSE: Durable synthetic leather backstay. Soft flexing upper shell materials for ultimate learn-to-ride comfort. COMFORT: Snow-proof internal gusset completely seals the lower zone of the boot, keeping your feet warm and dry. Room-to-Grow system features a removable footbed and a secondary integrated footbed to expand boots one full size without compromising cushioning or support. LINER: 3M Thinsulate insulation is constructed from high-loft fibers for water-resistant warmth that doesn't add bulk. SOLE: DynoLITE outsole with size indicator offers superior cushioning, improved board feel, and consistent support in a 20% lighter weight construction that can withstand repeated impacts.
