Primitive man I assume ran bare foot with the possibility of making use of some type of footwear such as wooden sandals or animal hide. Wondering how our ancestors ran and protected their foot before the running shoe, there is no doubt they endured immense hardships. However since its discovery, pretty handful of changes have been made for the humble running shoe. While the modern shoe might have not changed significantly other than being far more comfortable to wear; it really is intriguing to note that much more and even more research is being carried out in order to increase running performance.An intriguing article was published inside the "Journal of Sports Medicine and Physical Fitness" that carried out an experiment to understand how changes within the mechanical characteristics from the foot and also the shoe-earth interface affects
the spatio-temporal variables, ground pressure distribution and other parameters in bare foot operating. The other aim with the research was to examine if the Vibram 5 fingers shoes could basically mimic the effects of operating bare foot or not.

The plantar flexion movement will be defined as something that increases the 90 degree between tibia and frontal part from the body.
