at the International Lineman's Rodeo,like some of the teams from the U.K. wear them. If you are going or know someone that's going,it is in the middle of September. You could probably find out then. Also i don't know if this would ever work,but i have often wondered if it would work for concrete poles; there is a method of climbing using ropes on your feet that go around the pole and catch your weight to allow you to step up or down. I believe it is called the "Strobo method" of climbing. I have only seen it in books,never heard of or seen anyone nor heard of anyone that has done it or knows how. Be interesting to find out if you come up with something.
