The cleat covers protect the cleats, not the pedals. I have a set for my Look Keos. I rarely use them, however. I don't typically walk enough in my road shoes to bother with them. Look also started putting little rubber grips on their cleats. That makes walking in them a bit easier. I do bring them with me for a couple event rides I do where there is a bit of extra walking at the SAG stops, so from that standpoint, they are handy to have.
