Crabon sole shoe question.(7 posts)

Crabon sole shoe question.ol
Jan 14, 2003 4:43 PM
Just changed my shoes from sidi genius to shimano carbon sole and I noticed that after 2 hour plus rides I feel some sorenes on the bottom of my feet. Has anyone experienced the same thing.
Not necessarily the carbon solesKerry

The Shimano shoes have a good reputation for stiff soles and stiff soles are often a solution to foot pain, so it is more likely shoe fit. You might try putting the Sidi insoles in the Shimano shoes, or getting some other athletic insoles.

I would disagree with Kerry and say that soles that are too stiff (as the Shimano's may be for you) can be the source of foot pain. The Sidi nylon soles have a bit more flex than carbon soles and over the long term, some flex can be good for the feet and helps circulation. Or it could simply be that you are not used to the shoe, just like going to a new saddle, it takes a while to break in and get comfortable. I will say that taking the insoles from your Sidi's won't help, they are thin and won't make a difference, but an aftermarket set, such a Superfeet may help.

Good luck,
Ian

I've never thought of a shoe being too stiff, but I may have the same problem, too, with my Look "crabon" shoes. My left foot gets a hot spot on it yet when I use my mtb shoes or my Northwave winter shoes (nylon), this doesn't happen, even though I use look pedals with my road shoes and SPD's with the mtb and Northwaves.

I think it's a matter of shoe fit. Whether or not the sole is to stiff is really not as much of a question as proper fit. Where exactly does your foot hurt? How long have you had the Shimanos and how long did you have the Sidis for? Is it in both feet or just one? Are your feet wide or narrow? Is one shaped differently than the other? Shoe fit is an art, and there are much more important factors than sole stiffness. To the poster who said his MTB shoes are more comfortable than his road shoes, even with the flexy soles, that's probably because they're designed more for comfort and less for performance. Look at ski boots... a pair or racing boots like Lange L10s will probably be far less comfortable than a all-mountain boot like Salomon 1080s. That's because to get the max performance, not only is the boot stiffer, but it's much narrower. If the shoes are pinching your foot (even just a bit) after a while you'll develop a pain in the bottom of your foot usually about equal to the spot where your foot is being pinched. I.e. if the shoe is too narrow midway down your foot on the outside or inside, you'll probably experience pain on the bottom of your foot about midway down. I'm not familiar with the general fit of Sidis and Shimanos, but if someone could let me know if Shimanos are generally narrower, or just narrow, that could be your problem. Also, like someone else said, give your feet a while to adapt to the shoe, just like you do with a saddle. Another route is custom insoles, which will be very beneficial no matter what shoe you ride if you have strange feet or a tendency to pronate or supinate etc.

Basically, if the Shimanos are narrower (even by a little bit) that could be causing your problem. Sadly, there's nothing to be done about that, except get new shoes.
If it's a problem of adapting to the shoe, then you can either grit it out (the logical choice), maybe transplant the insoles from your Sidis, or get a stock insole like Superfeet, or a custom insole. The custom route only makes sense if your feet have weird characteristics.
Hope that helped.

Slide your cleats further back.dzrider

A former RAAM winner suggested this to me when I complained of hot spots. His shoes were redrilled to move the cleat under the front of his arch. I slid mine all the way back and the relief was immediate and I've had no problems since. He also suggested riding with orthotics if I had them.

My theory is that hot spots happen when most of the contact between your foot and your shoe happens at the ball of the foot and the contact between the shoe and the pedal occurs in the same place. Anything you do to spread the contact over more than one point helps.
Have two pair of Shimano carbon shoes. I found the inner solesPaul

to be uncomfortable. I replaced them with Dr. Scholl's inner soles, and it solved most of my problems. On a century ride, I'll get some soreness (use SPD's) from the cleat. The carbon sole is thin at the point where the cleat attaches, and they have a narrow toe box. Overall, I like them.
