I bought this after I rolled my left ankle after almost got run over by a car when running few months back.
I wore this support few times for TaeKwonDo practice sessions and it helped to stabilize my ankle when doing lots of twisting, turning and pivoting.
The downside is that the sole of my foot becomes sore wearing this for TKD, it seems that the strap is still too tight even at its loosest setting and digs to the sole as I have a very flat foot.
So am going to try either the sports ankle or the sports ankle dynamic (not sure which one) with the hope that it'll be just right support that I need without soreness.
