Features include our Merino 4000 material, a midweight cushion for perfect balance, reinforced underfoot for durability around the heels and toes, seamless toe for max comfort, and the perfect blend of stretch and compression to keep the socks in place and prevent slipping. The 74% merino / 19% Nylon / 7% Elastane material keeps your kid warm and dry in the coldest of temperatures. The cuff is 10” high, which gives plenty of room to seamlessly integrate as a protective layer between the boot and pants, providing adequate shin length coverage. Available in three junior sizes, the Drytex Merino 4000 socks are a perfect addition to any gear drawer.
