let us know what the diagnosis is.
after having knee mistracking diagnosed i can't ride behind anyone without looking at how straight their legs are. i see lots of people who's knees brush the top tube who would probably benefit from footbeds and the correct alignment, they obviously don't have any problems like i did but they would be a stronger cyclist if they had it corrected. it causes a muscle imbalance so that one quad gets overdeveloped and the rest get underused. weak glutes were part of the problem too, often the area of pain/discomfort can be caused by something one joint further up the chain.
talk to me about footbeds
