These are extremely functional and comfortable boots; however, the size has become an issue.

I bought them in size 8, and left them in the box to wear later, after they arrived. To my surprise, the boots have already stretched and expanded on their own to one size up, while still sitting in their original shoe box!!  I have never experienced anything like this with shoes/boots; and wonder should I be returning them or not.  I have injured my ankles and toes, so keeping my foot tight in their support, and have the supports comfortably fit in the boots is another matter!!
