    I am not sure that is a good idea.
    Most cycling shoes breathe pretty well through the top, and drilling holes in the sole is not going to increase ventilation due to insole, and may weaken the sole.
    Just my opinion.

    It will work if you start with a small drill and move up with larger sizes.

    Won't make much difference, though. Even if you have a 1/4 inch hole, how much air can get in there??
    If your opinion differs from mine, ..........Too bad.

    Buying parts to hang on your bike is always easier than getting fit.

    When I want to drill a hole I use a drill.

    I used to use an angle grinder, then I tried a welder and finally gave a food processor a run. In the long run I found that if I wanted to drill a hole, then a drill was the best option.

    As for drilling your shoes, I think you have more to lose than gain, but if your heart is set on it, then weld away. I mean, drill away.

    A Dremel will work fine. I use my Dremel to drill all the time, just put a bit in there and drill away.

    You might get better results by wearing better socks.

    @framesti,

    what you need is the Park Tool Sole-Holer, part number APR0110. It's a tool specially made from trilithium steel to take care of this task. Just be sure to lubricate the tool with pure whale oil or it will overheat and you'll torch the tool's warranty.

    How many holes are you going to make?.. You do realize that on top of the carbon sole is the insole, and then your foot... Either one of these will prevent air from moving through the hole I guess if you drill through both the sole and insole, the air would be touching your sock, unless you cut corresponding wholes in your socks! Now we're talking.

    Only benefit of drilling holes would be weight reduction.. About 2 grams, at the expense of a slightly higher coefficient of drag, unless you already always wear shoe overs, in which case, just take those off and you will have more circulation..

    If you really want better air circulation, drill holes in the top or sides of the shoe... Or just buy shoes with uppers that breath better..

    Actual benefit

    Nope. The benefit is that when you ride in a drenching rain, your shoes will drain instead of filling up with water. That's it. No cooling advantage, and like you said, no weight savings to speak of.

    ohh, I hadn't even thought of that one... you're right, that would be the greatest benefit.

    Do you have a link to what youre recommending? Do you mean like electric screwdriver? I guess I need carbide material?

    Yes. Use an electric screwdriver.

    But not carbide, for something as intense as the nylon or carbon composite used in the typical bicycle shoe sole, you're going to need a platiunum-iridium drill bit.

    I have to go now. My planet needs me.
