As of now, I'm not riding with cycling shoes - but rather with a fairly stiff-soled running shoes with superfeet orthotics in them. And I guess I need to work harder with those exercises! My doc gave me a couple to do. But she wasn't all that informative when it came to protecting my knees while cycling - other than don't ride with your seat too low. If anyone can recommend a cycling-knowledgeable sports med doc in the South Bay, I'd love to hear about it!
