Duck feet, knee injury and clipless pedals..help..

[Flur]

I'm going to have to go against the grain here and say that you should talk to your knee doc before putting speedplays on your bike. Speedplay Frogs actually caused knee problems for me (different problems than the ones I already had), because my knee needed stability rather than float. It took me months to get over the issues caused by only 20 miles on the Frogs. What resolved my issues was fine-tuning the adjustment of my cleats on pedals with only a little bit of free float.

I'm not saying Frogs aren't the way to go, I'm just recommending getting a professional opinion from someone that knows your knees. And if you can fix things without investing in another set of pedals, that's good too.

Also, if your foot turns out alot, you may run into issues where your heel hits the bike's chainstay. There is a product called "knee savers" which is a pedal spindle extender that threads onto the pedal and then into the crankarm. It basically moves the pedal away from the midline to give your heel more room. They work with any pedals that have pedal flats (they don't work with Crank Brothers or other pedals that attach via an allen key). You should be able to find them by querying Google.
