I switched back to Speedplay Frogs after a second attempt at SPDs, including a cleat fit by a physical therapist. The SPDs caused knee tendinitis both times. All gone now with the Frogs. You only have to grease the pedals once a year, and they suggest you put a few drops of dry lube on them after every few rides. I do that, it takes three seconds, no big deal. They are very easy to get in and out of.
