Adding a positive plug too for dirty girl gaiters, for the intended purpose and limitations Will sets out in the article they are very durable. I have used one pair for well over 300 miles hiking, trail running, and packing - on trail mostly but rough trail, rocky for sure and probably 20% off trail. They are still going strong - no loss of the velcro patch on either of my shoes (note the other comments about securing this with some stronger adhesives if you are having issues). And for $20 get a couple pair!
Another thing I like about the dirty girl gaiters is that they don't rub your ankles raw. The fabric is soft and so the top openings of the gaiters around an bare ankle, if you wear low socks trail running or hiking, does not bother you against the skin. That was not the case for the Simbliscity gaiters which rubbed by ankels raw during a 12 mile day hike.
Good review Will - gaiters are a small item but the right ones make a big difference in a workable hiking system.
