I have had the same problem for almost 10 years..... I found a strap similar to the one in your pic at Hibbets, that's the only place I was ever able to buy one. Now when I was in highschool one of our trainers would take the foam wrap, that you would wrap your ankle with before taping it, and start about half way up my thigh and wrap all the way down to my shin. Then he would roll the wrap down to my knee and then up to my knee also. It really works well plus you have to literally cut it off with scissors after a game.
