Someone pointed out to me today that my ankles sag inwards. After looking this up on the internet, looks like I over pronate, and will suffer horrible crippling deformaties in my legs and back as a result, or something.
How do I fix this? If I consciously try to walk more evenly on my feet, with more weight on the outward edge, will they get better? I already do yoga and stretch, but I'm probably not focusing on my legs/feet the way I ought to.
I'm not sure that I can afford to buy orthotics at the moment--are they really the only way to deal with this?
Also, I've seen the exercises in this thread
. Frankly, it makes me nervous. Do I have to do all that to fix this?
