I’m one of those who needs float so my knees don’t hurt. Shimano clips have little float and my knees hurt with them. Time ATAC and Crankbrothers clipless pedals have a lot of float and my knees never hurt. I can ride flats for about 15 miles but after that my knees hurt (or on long climbs unless I regularly re-position my feet). I speculate that sticky shoes and spikes on flat pedals lock my feet in just like a clipless pedal with no (or little) float and my knees need my feet to have float. I’ve seen this consistently for me in almost 30 years riding MTB.
