Are carbon soles on cycling road or mtb shoes worth it? [+ Giveaway!]

Are carbon soles on cycling road or mtb shoes worth it? [+ Giveaway!]

We examine whether higher power transfer with carbon soles (vs nylon vs rubber) is a myth? or is it more about comfort? Plus there is a double giveaway on fft.tips/strava here:

    Got to admit, my last pair of cycling shoes were a carbon sole, but I didn’t pick them due to "stiffness", but due to the fact they were on a sale, and looked pretty nice (in my eyes anyway).

    I knew that stiffer does not know more power. I have tried different shoes and I think comfortability is key in most situations – except for instance track racing 🙂
    But what do you think about carbon insoles that are supposed to stabilize the footposition? Also just marketing?

    Good information. Now we need a video on laces vs velcro vs boa shoe closures.

    Another great video shoe manufacturers don’t want us to watch. I’ve been wearing a Mavic with a full carbon sole for a couple of years and now it’s time to replace it I will definitely not go just for the most expensive full carbon anymore, thanks to you! Thanks for saving me at least 100 Euros.

    The most important thing is fit in shoes and placement of the cleat on clipless shoes. If you have a super stupid expensive shoe and it hurts your damn feet and not setup properly then what is the point, Right? If you are not a professional, or competitive rider I would say go with comfort over stiffness any day.

    Very interesting. Now you just need to bust the myth about road cleats giving the best performance over MTB cleats, unless you have done that already.

  21. Wayne Pilling on August 17, 2022 at 12:52 am

    When a sole goes up to 11, it just means it’s 1 louder.

    The Pro’s all wear custom made cycling shoes…. that look exactly the same the over priced made in China junk the large manufacturers sell to the gullible cycling masses….



  24. Makan Tahi on August 17, 2022 at 12:58 am

    sole is important only over pedal, rest of sole is waste, just to protect foot, i remember when carbon sole appeared in1995/6, only benefit was from shoe mass reduction

  28. Jura Stanić on August 17, 2022 at 1:06 am

    I had basic sidi with nylon soles.
    Hate the noodly feeling.
    And then i bought s works sub 6.
    Never looked back.
    You need to consider weight also.



  29. Darren Haines on August 17, 2022 at 1:07 am

    Guessing you didn’t check the science from Zero friction cycling before purchasing the Wend Wax?

    Size 15 feet hard to find a carbon shoe so good nylon has worked well glad to hear I have not lost watts. Lol



  31. George Farrow-Green on August 17, 2022 at 1:08 am

    Nylon soles over time begin to soften, carbon fibre over time has no change on the stiffness, the increased stiffness will improve comfort, power transfer and overall stability of the foot

    Cycling shoes for my exceeding wide feet is $400. Consequently, I use clips and running shoes and the harder I ride, the more my feet fall asleep. Any solutions come to mind?



  35. Reasonable Doubt on August 17, 2022 at 1:15 am

    Alex, 

    Thanks for your well made videos and trying to bring some science into cycling!

    I have some questions for you about this video:

    1. Wouldn’t any energy coming back from the shoe actually be released in the pedal upstroke and therefore be of little to no use? 

    2. I looked at the paper you cited for the energy loss data and couldn’t find anything about energy loss, only about the distribution of pressure. Could you in the future maybe post a screenshot of where exactly you get the data from?

    3. The last study you cite compares TORSIONALLY flexible shoes to stiff shoes. I don’t think that the results of this study can be applied to the question we’re actually looking at. What do you think?

    I love this kind of video, especially for me who can’t afford those high end part and love to destroy those super rich who buy anything expensive because of " bling factor" but justify it by saying " this could improve 23% this and that " in the group…



  42. HGordon on August 17, 2022 at 1:20 am

    Ok this may be a little late, but here is my comment. Having a soft sole is somewhat analogous to having rubber bands attached to your feet. If you are a sprinter and you need that power transfer you do not want to be working on a trampoline. Inevitably power in equals power out but there is a connection between you and the bike that is necessary for confidence. I would suggest choosing the right pedal with the right stiffness that works for you.



  43. Umut Birey on August 17, 2022 at 1:22 am

    what about mtb pedals vs road pedals ?

    I have an older S-Works carbon shoe I picked up when the new model came out. Super stiff. I just love it.



  47. Richard George on August 17, 2022 at 1:29 am

    I would like to see you apply a "sprinting load" to the shoe, eg. 300kg, mainly to see how bad the rubber soles would be. Good to know to science though. Enter !
