How to heat mold carbon cycling shoes and why all cyclist should have them!

Hey guys welcome back to my channel – in this video we heat mold the Lake CX403 cycling shoes! I have been using heat moldable shoes for the last 4 years and honestly this has been a game changer to my cycling performance!

If you have questions on heat moldable shoes email me at

    I have the cx 241’s yep it does keep the heel secure i was curious how much room your big toe has from the tip of the shoe and also do you crank your shoes down all the way? I crank them down thinking i might put more watts down maybe its all mental

    Think 10 times before you do the heat molding on LakeCycling shoes or buy them at all. This is what happened to my MX332.

    1. I bought $450 MTB MX332 cycling shoes from LakeCycling. Not a lot of money as such but still it is a top shelf price when it comes to MTB cycling shoes so one would expect a premium quality and a premium customer care approach.
    2. The shoes are said to be covered by 2-years Warranty.
    3. The shoes are designed to heat mold the heel in order to fit perfectly.
    4. In my case the heat mold is necessary since the shoes do not hold the heel.
    5. I decided to do the molding about 4 months after purchase and after few times of using the shoes in dry conditions.
    6. By precisely following the molding procedure provided by the manufacturer, one shoe at a time, I have performed the heat molding process. Unfortunately there was only a subtle effect of the heat molding as it seems that the heel material did not become soft enough to do this process – even though the temperature settings and time-in-the-oven was exactly like specified in the instructions.
    7. After performing the procedure the shoe toe in both shoes became wrinkled/damaged.
    8. I contacted the manufacturer – LakeCycling – with a claim.
    9. The manufacturer, just by looking at low-res photos, implied that the shoes were damaged because they supposedly had been used in wet conditions and improperly dried or overheated during heat molding process – which, according to the manufacturer, is my fault. Based on this "expertise" the manufacturer rejects my claim.
    10. The support person insistently kept on offering me 30% discount code on new shoes…only until I decide to take it – then the offer is retracted.
    11. The final solution recommended to me by LakeCycling is…. to go to a cobbler for assistance with repairing the shoes.

    How long do you have to massage the heel to fit it, and do you have to wait a period of time to let the heel harden up? The Lake instructions don’t talk about this. Thanks.

    Nice. And your oven needs cleaning too 😉

    I’m new to all this. Your video was very helpful in getting my 332s sized for my feet appropriately. Thank you.

    im getting the lake cx 241’s next week… they measured me i came at a 42.5 but im going with a 42 in the 42.5 i had like half inch room from my big toe to the top of the shoe….i was curious how your lakes fit on you and where your big toe is and how much room also?

    200 degrees? You mean 200 F or 90 degree?

    Dude, that oven is GROCE !

    My question is about the moldable heel cup in the CX241X. I’ve got two new pair-43.0 and 43.5-to choose from. The 43.5 feels great in the toe box but has a little heel slipping when I walk. The 43.0 feels ok to good in the toe box and the heel is less slippy. How much difference will the heel molding make? Thanks.
