The results of my recent thesis project revealed that carbon fiber shoes raise the peak plantar stress on the forefoot (mainly at the MTP joint/"ball of the foot"
by 18% over shoes made without carbon fiber materials. My theory is that the lack of flex in the carbon shoes causes the force to focus through a smaller area, thus increasing the force-per-area or stress.
I also performed two types of stiffness measurements on the different shoes and found the carbon shoes to be much stiffer. Does anybody else have experience with plantar stress as it relates to shoe stiffness?
