Appreciated, Hermes. Don't be lost, it's not that hard. I don't clip in. I don't own clip pedals, cleats or shoes and I never have. I've been on platforms with clips/straps since being a kid, well we won't discuss age. The pedals have been Sheffield Strada (Quill), Campy Strada (Quill), Campy C-record Strada (platform), Shimano 600 6207 platform, Lyotard Berthet platforms, and MKS platforms. My feet have rarely not tracked the pedals, but when they have not, I revisit saddle position. My feet are usually a little pronated, but not enough to cause heel impacts. I can also try tighter straps (incrementally tighter). My best crank length has been 170 since before high school, but this particular bike might be wearing 172.5 now. I have felt a slight difference between the two lengths, in the past.
