I wear high leg lace up miltary boots, the current ones are German army, the previous ones were UK, they were tested to extreme on one occassion and held up well, taking the front bumper off a car and wrecking its drivers door,I didnt fall, but my boot sufferred even though it saved me, great on the bike, you "get away with it" when off the bike ( i use them "under the pants" and they are (of course) great for lots of walking if that occurs, to waterproof them (and this realy realy does work), I use a product called "Duckwax" but I have only seen it at shows, its probably online, but the product last so well even if initially quite expensive, that I can no longer read the label on the pot, it takes a few goes, say three applications over a week, and then occassional re-apply, but its 100% effective, I also use it on my leather pants, to great effect and did try it on gloves, but the waxy finish doesnt suit in that item.
