My daughter always has worn a size 10. For the first time, they were too small. Unfortunately, I have now waited too long to return, but we have never had a problem from other Amazon sellers for a size 10 sandal. These will have to be discarded and we will just have to find a more accurate Amazon seller with the correct size.

Ex Output:
negative


Ex Input:
This coloring book is wonderful. Each page is totally different and offers lots of challenges. I love the sheet between each page that helps you find the right colors and separates your work from the previous page. Love it.

positive
