My son is one, so he is walking, and although the picture clearly indicates a non skid bottom, these socks do NOT have one! While they are good quality socks, they are also slippery on hard surfaces.  So if you have a walker, order something else.  I only give these 3 stars because they are giving the wrong impression by the pictures.  I need something for my son to not slip!!  Disappointed.  Next time I'll just go back to old navy.
