Details: The industry standard for cold weather warmth and comfort, Carhartt Kids' Heavyweight Wool Blend Boot Socks are fully cushioned on heels, arches, toes, insteps, and legs to keep kids warm and protected from the elements. Made with Cordura fiber technology and abrasion resistant yarns in heels, arches, and toes adds, these heavyweight kids’ socks were built to last. Mesh insteps allow feet to breathe and sweat-wicking technology moves sweat away from the skin to keep feet dry. 8% temperature-regulating wool blended with synthetics feels soft on feet and legs. For all-day comfort, heel pockets hold socks in place and arch supports keep feet feeling fresh. Available in two kids' sizes: Medium (US Kids' shoe size 12T-2.5) and Large (US Kids' shoe size 3-6).
