    question on shoes/pedals

    Went into my LBS to buy some shoes and pedals last week.
    The guy fitting me (had my bike in for a fit as well) didn't like the way my knees were lining up with the shoe/pedal combo while I was on my bike on a trainer. His rational being that my knees were pointing inward and he wanted to space my feet out a little more?

    He added some shims to the cleats and then added what looks to be spacers to the pedals (see pic ).
    Is this common? Does it compromise the strength/structural integrity of the pedal/crank connection?

    Every fit system has its theories and practices. No "one" system is totally correct.

    Regarding your pedals: if you weren't experiencing knee pain, I wouldn't have bothered with the pedal extenders.

    Will the extenders damage anything? As long as they have complete engagement in the crankarm and the pedal has full engagement in the extender, I wouldn't worry, even though there's extra leverage on the crankarm.

    Try to watch a bike racing video and observe the knee position of various riders. Then if possible, get on a trainer or rollers and watch yourself in a mirror to see if your knees do anything excessively weird.

    Thanks Peter.
    To the guy's credit - I did feel some discomfort to the inside of my knee prior to the extenders being put in.
    I went for a 50km ride the day after purchasing the pedals/extenders/shoes and everything felt great.

    a small shim is fine, because you have plenty of thread engagement between the pedal and crank arm.

    If the shimming of the pedal compromises the thread engagement too much, some pedals have longer spindles that can be swapped on to.

    To refer to an old '60s expression and to amplify what others have said: "If it feels good, do it." Sounds like the extenders (or pedals with longer axles) are right for you.
