My daughter wears a size 5 toddler shoe and I ordered the toddler size 6- I figured they should fit perfect by summer. I was so excited when they arrived. Good thing I tried them on her right away rather than wait and have it too late to return them. I will acknowledge that they arrived in good condition and very quickly. However when I put them on my little girl's feet they were WAY too small. The straps fit fine but her toes stuck out over the edge of the sole by a good 1/4 inch and the heel stuck out over the edge by a good 1/2 inch. I had to return them. At least they made my return easy. Too bad these didn't fit, they were really cute. I wish I had gone at least 3 sizes bigger. Her size 4 sandals from Babies R' Us fit better- much larger sole- and she had definitely outgrown them as the straps pinched her really bad across the top of her foot. The only good thing about the fit is they didn't hurt her.
