I think I know what you mean. My left foot doesn't feel seated properly, usually because I push the strap forwards a few times trying to get my foot in. I don't get it all the way in, so the strap sits forward a bit and doesn't secure properly. Trying to get your foot secured while riding in traffic can be a PITA and it's why I have to feel around w/ my foot w/o looking at what I'm doing.
