Ditto what Rob said...except I didn't get mine until 1998 (I think). I've used ShoeGoo on them after I heated them up too much by the campfire and they seem to be in pretty good shape again.
I didn't see the other choice - Cowboy boots, with rubber soles, of course.
Then on the dirt bikes, we used our hiking boots.
Graham invested in a custom made pair of Bates boots back when he first started riding and still uses them.
