Fit my 5yo and 7yo just fine. They are both about size 12-13 shoes. I was also able to squeeze into them and I’m a size 7 in womens. They were warm and kept them dry while skiing. Washed them afterwards and still look good.

I bought Xs for my almost 3 year old and they were too big. We will hold onto them for the future because they are great quality. Just bummed we can’t use them this year. Plus we were sent 2 different sizes.
