Helmut Schaub had some beautiful military-like boots on his Safari character (under "morphs" in the funstuff pages--go figure) which he borrowed from someone else (I can't remember at this point). I'd do a search for "safari" and check out the figure--maybe the creator of the boots are listed in the readme files. You could use the grouping tool to spawn a pair of boots from the Safari character if you can't find the originals.
