Flat feets and inside knee pain with clipless
I recently purchased new clipless shoes (low-end Northwave) and pedals (Shimano SPD-SL) and after a few rides, started developping pain on the inside of my knee (not "into" my knee but on the inside part of my leg). I've tweaked the alignment of my clips to make sure my feet are not pointed outward too much - they have to be a little or else I develop pain on the outside of my tibia. It seemed that I would have to choose between inside knee pain or outside knee pain and haven't found the "sweetspot" yet.
Last night however, I had a moment of clarity and realised that my inside knee pain is pretty much the same that I get when I run with shoes that don't offer enough arch support. My PT said a while ago I have flat feet and need proper footwear for running. Buying a pair of shoes with a lot of support solved the problem. So I guess that would apply to biking too. Is my reasoning logic or since the pedaling motion is not the same as a running motion, having flat feet is not really an issue (since almost all pressure is on the ball of the foot) ?.
If the issue is really with my lack of support, I was thinking of getting Superfeet insoles (Insoles | Superfeet), as I don't want to buy another pair of shoes. Do you think it's a good idea? Has anyone tried them with success on road bike shoes? Those insoles can be pretty big and road bike shoes aren't, so I'm a little worried about the fitting.
