Using clipless pedals again. Getting a little knee pain. Nothing too bad however clearly something amiss so best to try and iron it out before it does become a problem. I know that pain in different places can indicate possible causes and therefore solutions but haven't a clue what they are. Basically pain in left knee on the right side (ie side which points towards the right knee as opposed to the one that points outwards) and it feels like its coming from the area just below where the knee bends. The pain isn't affected by touching and it isn't constant just comes and goes every few seconds. Have tried to use these in the past and one 5 miles trip would have left me hobbling for weeks and certainly off the bike for that period however after advice on here I was able to get more angle from cleat on the sole of my shoe which allowed my very toes outward feet to take a more natural angle than the shoe would otherwise have allowed. There is definitely a transformation now as I have worn these now for over 120 miles over the last week and can still walk without problem except for this niggling little pain. Any ideas what are the most likely causes of this?
