The main function of human skin is to protect the body by means of a barrier that prevents the exit of all body essential elements, like water, and to avoid the entrance of external substances (microorganisms and prejudicial elements, for instance).
Our feet have a very special function: they support our body weigh during all day, during work and leisure, and they are forced to long periods of effort, very often inside nice but uncomfortable shoes.
