When we're cold, our vessels constrict, keeping our heat closer to our core and resulting in our feet feeling cold. By wearing socks and keeping our feet warm, we're promoting blood flow to our feet, which is essential for foot health, injury healing and more. It also protects our feet from things like blisters, corns and calluses through their protective and pressure-redistribution qualities. We have 125,000 sweat glands on the bottom of each foot. Extra moisture can cause painful blisters, nasty odours, as well as fungal infections. HOTTEST Socks pull this moisture into their fabric and away from the skin of the foot, so this is another way that socks keep our feet safe from unnecessary harm.
