The shoes are a bit wide for my feet, I typically wear an average sized width (not narrow or wide) without any issues but my feet are sliding around in these because they are a bit too wide for me.  They are also about 1/2 size too large,I normally take a size 7, never 6 1/2, but these run large in the length.  I took off the heel strap because it just flops around and doesn't provide any support.  I am rather disappointed, thankfully they weren't as expensive as other vionic brand shoes but I would not recommend these unless you are able to get a 1/2 size smaller than your usual size and do not mind the width being larger than normal.
