Ordered these socks for my grandson (he is 2 1/2). He's a big Bubble Guppies fan and really likes these socks. They are very colorful and contain all the important BG characters. The fit and thickness are perfect for his shoes. There are no rubber nubs on the bottom to prevent slipping on hardwood floors, but we wanted the socks to be thinner so this wasn't an issue for us. If your child is walking around the house in socks and your floors are slippery, this could be a problem.
