The shoe did take some time to get used to. I know I had some sores on the top of my foot after wearing them the first and second time. I also realized they are really tight! Which is okay for me because I do have skinny feet, however even with the skinny feet the heel kind of rubbed at times too but now when I wear them they are feeling much better! I still can't wear them all day without hurting but they are still nice.
