When you have shoes that don't fit properly, your feet may end up with unsightly and painful corns and calluses. Corns and calluses are created when a portion of your foot has too much pressure or friction and hardened skin builds up to protect the foot. Calluses can simply be filed to reduce them using electronic or manual callus files. Corns require a special type of treatment to help reduce or eliminate them. Corns tend to be painful and are smaller than calluses. They generally develop in non-weight-bearing areas such as the tops or sides of the toes or even between your toes. Corns have a small hard center surrounded by inflamed skin. When you start your Instacart order for corn and callus treatments, add products like Dr. Scholl's corn remover pads or liquid with salicylic acid to remove corns and Tweezerman file stones to help get rid of calluses.
