I'm just trying to anticipate problems before they arrive. I don't know the degrees, but I toe out enough that my track coach (20 years ago) tried to correct it. After running sub-47s in the 400, he said "ok, just run then." Anyway, with my knees straight, my toes are at between one and two o'clock (vice versa for left side). With my Rans Stratus, (platform pedals) there was no problem (except for my own mistake of churning big gears uphills which caused knee pain). But I am buying a Cycle Genius RDX that has clipless pedals (not sure exactly what brand or if it's CG brand). I will try them out and see. I may switch to Shimano M-324 clipless and adjust them to loose to allow for some play (I've received some excellent tips on this website- maybe eventually I can contribute as well, instead of just drawing from it). The KneeSavers can be a last resort as you said. I just like to plan ahead. Can you explain what you meant by "..the bend should be about 15 degrees BDC"?
