I wear a 8.5 M and I don't have wide feet or bunions but I followed my mind and got a 8M glad I did I wouldn't be able to fit a 8.5. Because they are pointy toe I suggest goung a half size up. The sides of my feet by my pinky toe is hurting after just walking around the house so I will try and stretch the front our a little. I might have to wear  a bandaid or something to stop that from hurting.
