Been on clipless since around the late 80s when I bought some Looks from Performance or Nashbar (using the quaint thing called mail-order where they sent you catalogs with the order slip in the middle). Kept my traps/straps on my commuter. With my old Avocet cycling 30 shoes they work fine. If you didn't tighten the strap it wasn't much different from being on a platform pedal.
