PUMA Kids' 6 Pack Low Cut Socks - Breathable Cotton Athletic Socks for Boys & Girls - Perfect for School, Sports & Everyday Wear

The quality, comfort, and style of the sock is excellent. Absolutely no regrets buying them and no hesitation in recommending them. In fact, I just bought a second set.Sizing is confusing though. It is supposed to correspond to age, not shoe size. If you think of it in terms of girls age, then I think it's pretty accurate. I bought the ones sized 5-6.5, and they fit my 3.5 year old boy just fine, with enough stretch to least until he's probably 5. So with all that said, I would size these at girls 4-6 years old and boys 3-5.
