I've been road riding for 30 years (now 68 yo) and always used clipless. Had quite a few bike fits & cleat position was generally unaltered; Shimano SPD-SL yellow 6' float cleats with my toes pointing very slightly inwards (about 3').
A year ago I had sudden right knee cap pain, saw a specialist who diagnosed arthritis but said to carry on riding & back off if it hurt too much. He was also a cyclist & suggested using Speedplay pedals to increase the float. Initially I changed to 150mm cranks & increased saddle set-back from 70-100mm & this seemed to help a lot but still had painful twinges. Rather than buying Speedplays I modified my SPD-SL pedals which enabled an increase in rotational float to about 20'.
To my surprise, when using the modified pedals both feet point inwards by a whopping 15' (estimated). It doesn't feel odd but I'm wondering if such a radical change may have negative effects; I've only had 200 miles on them so far.
My mate did the same on his mountain bike only his feet ended up with toes pointing outwards. It has the added benefit that a sideways flick releases.
