I bought these boots for my 5 year-old daughter that wears a size 13. I bought them in a size 1 to make sure they fit her through the rest of winter. These are the cutest boots! They look even better in person. The colors are vibrant and fun. They are very well made and I love that she can wear them in snow and rain! I also love that she can put them on all by herself. No more struggling with shoving a boot on her foot. They fit her feet really well and she says they keep them nice and toasty. I'm very happy with this purchase and would recommend!
