I have a pair of low cut Sodhoppers that I couldn't be more happy with. Paul will customize your boots for you in almost any way you want and they fit like they were made just for you because they are! His prices can't be beaten for this kind of moccasin as well.

This is the only picture I could find on his site that showed tall black boots. He offers several kinds of soles.
