Followed the sizing guide, still runs small. I would take a size up and not order if your baby has chubby feet like my girl. She is 17 months old and wears other size 5 shoes and sandals. The 5's were too small and so narrow. I wanted to go to a 6 or 7 but I had a feeling they would still be too tight for them. I liked their look, we had multicolored ones and they were very pretty. We went back and ordered different shoes. If they were available I would definitely order!
