I have noticed my knees aching a bit in the course of a couple of rides lately. I gave it over to the cold, the damp, old age and figured that it would get better or it wouldn't. It always seemed to clear up right away, so I didn't think much of it. This morning one knee seem to continue to be irritated longer than normal. I really need my knees!
It finally occurred to me that my summer road shoes have inserts that were put in when I had my bike fit. Because I supinate, I have shims in my shoes to keep my knee straight when I pedal. I have been riding all winter at high cadence and high pressure without them. It's probably because I have such good knees to start with that I hadn't had problems up to this point. I have almost a 3 degree change in my foot angle. At least it is an easy fix.
I "stole" the shims from my summer shoes and put them in my commuter shoes. That should be it. No more aching knees. I also verified that my LBS stocks them, so I can outfit both pairs of shoes. My LBS is still in possession of my bike right now. *sigh* I can't wait until it's done. Not that I will ride it right now but there is an empty place where it hangs. It looks like I will be around the same mileage as last month. It's a little low but still more than some people drive in a month.
