I have a question though. On every sample movie those guys play with their socks... I can pull some out that way too, but from the moment I have my shoes on, my feet get *way* too big and I can't pull none anymore... Help?
Being able to do this technique with shoes on will become easier over time. Work on it with your shoes off for about a month. This way you should really have it down, then try it with shoes on.
