I searched for many hours looking for just the right shoe, and this seems to be the one.  I ordered a 11.5 4E  - I will say it must run a  little small because I normally wear a size 11 and the width was not wide enough.  so I ordered a 6E which is sufficient but barely.  My brother-in-law was visiting tried on this shoe and it fit him so I will not return but again he normally wears a shorter and not so wide shoe.  I am very happy with my 11.5 6EUS.  The shoe is just as described and perfect for assisting my artificial knee to keep from twisting.
