I thought these socks would be a good choice due to the easy sorting system and lack of color matching. I've gotten to the point where sorting socks for eight kids is a huge task. But I was disappointed because these are really poor quality socks. They began to fold and stretch in strange ways and contract in other strange ways. We have a medium size for my 6 year old daughter who wears size 12.5 shoes. They fit her really well except they dig into her calves unlike any other socks we've had. Her feet were red and irritated where the sock ended at the calf. Plus, they cling to places like they crave it! I definitely wouldn't recommend these socks to anyone. We've had them for less than a month.
