Do European's have different proportioned feet than we do?? I can't seem to get the size right ? I am normally a perfect size 8. So all the reviews said they run small better get a size larger. Next size up was 9/10 so that s what I ordered only to find out they are too long. However the thong strap is snug. If I had ordered the next size down 7/8 I'm afraid they would have fit too tight. The bumps are fine. They don't hurt but I don't feel anything therapeutic happening. Not worth the price and  Just ok.
