"For flats and heels I usually wear 8-8.5. For tennis shoes and boots I will buy 9. So I bought an 8.5. I was immediately surprised on how narrow they are and how tight they felt when I put them on. They felt like some other shoes I recently bought that were size 8. They seem to be well built but pretty firm feeling. Because of that, I feel like they would a while to break in. I am also a little worried they might give my 32 year old foot a bunion. I am going to return them and look for something else."
