Most people suffer from perspiration and can't stand it. In addition to causing an unpleasant odor, foot transpiration causes the growth of bacteria and fungi in the fingers and infectious diseases. The warm, humid environment inside the shoe is also a good place for bacteria to grow. Nowadays, due to the importance of the health of the feet, different methods such as using the nanoparticles for socks are considered. Such socks do not cause an allergic reaction and do not harm the human body. Nanoparticles react with the outer membrane of the bacteria, causing structural changes within it and eventually destroying it. Nanoparticles are contained in the full volume of the fibers and remain active for the entire sock life.
