I have look 206 pedals and an orbea frame with straight chain stays.i'm having a problem with the inside of my shoe rubbing against the chain stay.is there any correction that can be made to eliminate this problem or do i have to retrain the pedaling angle of my foot? my shoe also rubs against the cranks as well.

Take the opportunity an improve your form... feet rubbing against the pedal is due to too open angle. Think about pointing your toes inward and having slight rubb of your knees with the top tube. Then open your knees just enough so that they are not touching the top t. during the stroke. Now, you'll looke like the pros :-).... and you'll stop hitting the chain stay.

should i set the angle of the cleat with the heel out to help with correcting the open ankle problem?

Trying to change the way your feet point while pedaling will only wreak havoc on knees and foot tendons. I cannot stress strongly enough my disagreement with the advice above. Knee position for pedaling efficiency is one thing, but feet placement should be NEUTRAL to your regular walking position/natural biomechanics.

I have a fused left ankle, and rubbed the "Ultegra" right off my crank because that foot toes out a little. I went in for a professional fitting with a sports medicine biking specialist and he put some shims under my cleat and got my foot away from the crank a teensy bit. That's all it took. But he didn't adjust my cleats to fight with my natural foot angle.

If you are in a big city, cough up the dough (mine cost $125, but with a disability I wasn't screwing around, and even good LBS's get clueless when you have a more unusual fit issue) and find a pro.
cleat adjustment time?Tig

Sounds like your cleat might needs a little adjusting to push your foot out away from the crank arm and chain stay. While peddling, compair the gaps between your shoes and the crank to see if there is a noticable difference. You don't want your feet too far out from the center line of the bike either. I think the distance from the center to your feet is called the Z axis.

Maybe the cleat just needs to be repositioned a little to angle your heel out some. A little adjustment goes a long way so easy does it.

Do you have flat feet? Sounds like you do if you're rubbing on the cranks. If you do have flat feet the best thing you could do is get an orthotic like a Peterson foot bed or the Superfeet brand. Some aluminum frames have large chain stays and this could be the problem with hitting the bike. I had this problem with my Cannondale and and put a 1/8" washer between the pedal and crank arm. You could buy the Look carbon 256's that have a wider stance. You get about 1/4" further from the bike with the carbon 256's. They don't sell them anymore but you could check the classifieds, I think there is a set for sale. Good Luck
