Remember to order if your child is on the verge of size. My daughter is 4 and has been wearing baby shoes for 9 years. I ordered 3-5 years. When they arrived they were perfect so I washed them and they have shrunk and are now unusable and also washed out the paint on other things in the load even with the paint trap. However, I love their fabric, colors and design so much that I gave this set to a neighbor and ordered a size up. My daughter loves wearing mismatched socks and it cheers her heart up and makes mom a little less nervous!
