The Full Tilt Growth Spurt Adjustable Ski Boots grow with your kid's feet! The Growth Spurt youth ski boots can be adjusted to 3 different ski boot sizes to grow with your kid’s feet & save the family budget while reducing environmental impact. A first of it’s kind for kids! It even includes FT's Quick-Fit™ liner with Intuition® foam that molds 100% to feet for warmth & comfort like no other kids ski boot in the world. They’ll be able to ski longer by staying warmer, in more comfort. They are also easy to get on and off like sneakers. The Growth Spurt Adjustable Ski Boots are great for progressing intermediate junior skiers that are still growing. The adjustability technology does add a significant amount of weight to the boot. The authentic 3-piece design features a free hinging cuff & ribbed tongue for the same one-of-a-kind natural ankle flex and shock absorption as Full Tilt's adult boots!
