Bone-chilling temps and Arctic storms call for the ultra-warm Columbia Girls' Powderbug Forty Print Boot. Made to handle the harshest conditions winter has to offer, this boot features a hefty dose of insulation and a thick removable felt liner to keep your kid's feet toasty when temps are well into the negatives. Meanwhile, the waterproof upper prevents heat-robbing moisture from getting in, and the rugged TPR outsole helps her maintain traction on icy surfaces.
