    Any way to stiffen the sole of cycling shoes? (stiff inner soles?)
    There's only a few cycling shoes available in my size (50-52 depending on shoe) and my current shoes (Shimano M087) could do with being a bit stiffer in the sole. I use XTR race pedals and the small platform is quite obvious through the sole of the shoes. A carbon sole would be great but I don't think there's anything in my size.

    I'm wondering if there's any way to stiffen them up or aftermarket inner soles that are really stiff but still comfortable?

    Back in the day when it was a general issue, I made carbon fiber inlays for my shoes.

    Maybe you should try the same.

    You gotta be a wee bit more specific, to give me a chance to answer that question ;)

    I guess I'm wondering exactly what you mean by 'inlay'? Something in addition to the inner sole? Below it? Attached to it? What shape and thickness did you use? Did it just sit in the shoe or was it fastened somehow? Where'd you source the carbon fibre? How'd you layer it etc?

    Thanks!!!

    I put it below the inner sole, it was glued in, it took up the space of the front half of the shoe.

    As I recall, I made it 2.5mm thick.

    Carbon fiber can be sourced loads of places, depending where you're situated. I usually buy composite materials from Fibermax Composites.

    The layup was twill 45-0-45-0.

    Thank you very much good sir. That's what I was envisaging. I actually have a podiatrist appointment soon, to follow up on my orthotics, so I might mention it to him too.
