Socks do affect the function of your feet: they can restrict your toes just like shoes can and they cover your nerves inhibiting your sensory input. So finding time to be both shoe and sock-less is an important part of improving your overall foot health. Many people, myself included, often go completely barefoot in their shoes.
But if you want to wear socks, you certainly can! I wear socks in the cold months and sometimes to make my shoes fit better. It’s just a good idea to find socks that let your toes spread out so you get the full benefit of your foot shaped shoes. Find a list of many different foot-friendly sock options below.
