I normally wear 8 or 8.5 shoes so I ordered size ten and the inner lining was painfully too small, in both length and forefoot width.  The outer boot was actually a bit big and would required >3 thick socks to be tolerable to wear without the liner.  The problem seems to be that the inner linings are sewn freehand so many run small as only a small error in stitching markedly reduces the inside diameter of the lining.  I probably could have re-sewn the lining by hand but that's too much hassle.

Outer boot itself looked pretty good for the occasional wear that I was anticipating.  I was afraid to order 3 sizes too big, so I requested and received a prompt and full refund.  BTW, if you open the package carefully, it is already designed to be used a second time so it was a breeze to return.
