I really like these socks for my very active 2 1/2 year old. I have actually used these socks since he was a baby also.  They stay up well and I like the grippers on the bottoms because we have tile and wood floors and if he is wearing socks without them he is falling all over the place.  They do come with 3 different patterns of stripe at the top which is a pain when it comes to laundry because you have to find the exact match instead of just having all white or all grey stripes.
