I have a  fairly slim foot with a shoe size of 9 1/2 - 10 and often have trouble finding a good fit. After much review and pondering I ordered the size 10.  The moccasins were a perfect fit in both length and width.  There is no binding, or excessive tightness.  The leather in the moccasins is rather stiff out of the box, but is rapidly becoming more pliable as they are worn.  They appear to be sturdy and well constructed.  I expect to get much good wear out of my pair.
