I was at therapy today working on my knee and my therapist noticed that I have "flat feet". He said that having flat feet and being active is what causes tears in the lateral meniscus (which is what landed me in surgery, then therapy). That means that I MUST wear arch supports or else I'll be tearing myself up all over again. I'm a dancer (mostly tap), and [most] dance shoes are made to fit your feet like a glove on a hand -- there wouldn't be any room for arch supports. My dad told me that having flat feet can hinder a physically active individual's life unless they wear arch supports. Is this true? I'm wondering if having flat feet can hinder a dancer's life. Would having arch supports improve your arches or would you have to wear them forever? I heard that ballerinas are always trying to "improve their arches", is that true? How do they do it (if they do)? (I'm not a ballerina, so i don't know for sure, lol) Also, am I getting all worked up over noting? Will i just be fine?
