Received for my granddaughter who is 7 years old and wears US size 6.5. I bought size M/S size 8-13. I measured the shoe and it is only 7 inches long so it's not even 8 inches to be considered the size described. I thought they were a bit small so I took the size I made because he said it would fit a size 8-13. She won't be able to wear them at Christmas, which is what they're for. I do holiday shopping early.
