injinji Kid's Sport Lightweight Micro Socks;

Happy feet make happy kids. The KIDS SPORT LW has an ultra-thin, second-skin fit that allows tiny toes to align and splay naturally. The unique 5 toe sleeve design and light breathable moisture wicking fabric keeps feet dry, cool and protected from blisters. The micro length rests right at the ankle and features a comfy dual welt band to hold the sock in place. It may take a few minutes to try on their first pair, but it's never too early to start proper foot care.
