Evolution of Shoes (functional shoes)


Although the exact period of time for humans to start wearing shoes is unknown, since mankind invented needle and made clothes to wear 25,000 years ago, we can estimate that shoes made appearances around this time.

Just as clothes were invented to protect our bodies from the cold and hot sunlight, shoes were first developed in cold areas and hot desert areas to protect our feet from freezing or heat from the surface.


Shoes originated from tying and wrapping our feet using a bark, grass, animal skin, or animal hair, and slowly transformed into a fixed shape, and shoes are currently evolving into more functional form, which is more excellent than basic functions of basic shoes.
