How can you become involved with the ballet world besides dancing?

I have always loved ballet and it is something I have always wanted to do but my parents could never afford to pay for lessons. Now I’m 27 and I still really love ballet. I want to get involved and experience some of what I missed out on. Problem is, I have a foot injury that prevents me from physical activities like dancing. How do you think I can best become involved in the ballet world besides dancing?
