My daughter has a lot of health issues and swelling of the feet and legs is one of them.  She usually wears a size 10 but these run at least a half of a size, if not a whole size to large.  They are super roomy for her swollen feet and love the ankle support!  Besides that,  they are built with quality in mind, but after all,  they are Ariat's!!!! So we are exchanging for a smaller size.
