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

I have the wedges from Bike Fit too. I can't praise them highly enough. I also have feet that point out. Going clipless, my knees went way in. With time, my right foot started killing me.

The wedges fixed all of that.

Utterly amazing.

My two cents,

I have had my ACL reconstructed twice. I'm super protective of my knee and had my cleats adjusted so that I was absolutely not in a position that would stress it. I have no medial or lateral collateral ligaments on that knee so I have to be very conscious of my position. i'm not sure what kind of cleats I have but I do know that I wear sixsixone shoes. I do have duck feet but more than the clipless system, my bike fit hurt me. When I was fit for my bike, the ideal position for me made me knee flex too much at the top of the stroke and put way too much force on my knee cap and knee joint. so I had to have them help me find a position that afforded a little less flexion. you might want to check that. Too much flexion at the top of the pedal stroke and then pushing down puts a lot of pressure on your knee and will stress that joint...especially without an ACL. Good luck.

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.

My left foot turns out a bit and I ride SPDs on both bikes. I just adjusted my cleat a bit.
