So glad I found these socks for my toddler!  I had a really hard time finding socks that were large enough to stay on her feet and also have the non-skid bottoms.  Seems like most brands have non-skid bottoms in the baby sizes and not in toddler sizes, which makes NO sense to me.  These stay on her feet whereas she was able to pull most other socks off too easily.  They fit well with her shoes too.
