My intent was to see if I can achieve even more stiffness through the carbon sole. I have a Specialized S-Works Road Shoe model in 2013 and have to say that they fit me perfectly. The sole has expanded the middle shoe area, which is probably intended to ensure greater comfort. This I liked but absolutely not, because I have a standard foot which is rather narrow. Also Wehwechen I do not have, so that the sole like a foreign body was and I have therefore sent back.
Since one can only the recommendation itself to test!
