My Campy NR pedals are 40 years old, with probably at least 10k miles on them, maybe 20k, and show no signs of failing. Many pedals have a tab on the back side to assist with flipping them up to put your foot in. I would look for some used vintage pedals (Suntour, MKS, Shimano, etc.). Here on bikeforums is a great place to pick some up. Seems like many modern components are designed to fail and are not rebuildable

When I ride clips/straps, I usually do not tighten the straps much at all anymore, and don't have a problem with my feet coming out unintentionally. YMMV.
