I could not get the heel to fit snuggly despite trying inserts and thick socks..I got these in a timely manner,..they looked better than the picture. I was amazed by how comfy the inside was. I am a 10 wide womens for almost every shoe, save a few dress shoes where I go down to a 9.5 medium. I have tried the heel inserts in the past and they are never really a true fix. I wanted them when I go out golfing and the course is wet, hence being comfy and a snug fit were important. The front fit great even though they do say 10 medium width..nice and snug but not too tight. I doubt that going down to a size 9 would make a difference as when I get a men's shoe I wear an 8.5. I saw this issue in at least one review so perhaps they could build in a  "flap" that could be cut off if you don't need it. Even though I have a wide foot, my feet are a actually "thin and bony"..(if that makes sense)..instep is NOT high. While I did return them, they are way better than I thought..stylish as well...hence the 5 star rating...also wanted to use these to walk on muddy trails.
