I purchased these in a size 4 for my daughter in October. At first I thought they were too snug. She was 1 and a half at the time. About a month later I decided to put them on her to see if they would mold to her feet and with about 3 or 4 times with her wearing them & walking in them all over the place they fit perfectly. I love how comfortable she is in them, I don't have to worry about her tripping over her own feet. She has worn these shoes indoors and outdoors to play, even got them wet, but they have not torn or come apart. I highly recommend them. Her father even suggested I buy her another pair in a bigger size since she's beginning to outgrow the pair she has.
