Sorry about the EBs! Those steel shanks along the soles make wall work so much more reliable: standing on what we call "five and dime" flakes becomes possible. However, they are worn so very tight that the feet can become numb. It looks like my other boots are Boreals... grey with red emblem. The soft soles are great for waxpaper faces (like the apron of Glacier Point), but I have to confess to an occasional lack of style with them (there have been times where the only way I could get through an area was to go up faster than I was going down). If you are planning to do animations of climbers, the type of boot will be critical because that will govern how and where he places his feet. If you are going to do women climbers too, email me (hauksdottir@earthlink.net) and we can talk about the difference in technique. I've never done a pullup or chinup in my life but I could lead 5.7 and follow 5.9 routes. Carolly
