A shoe bite is a blister that appears on the foot, because of new or tight shoes. Not only do these shoe bites hurt when you stand or walk, they could also leave behind unsightly scars and affect the overall appearance of your feet.
The main cause of a shoe bite is wearing shoes that may be a bit smaller than your actual foot size. Shoes that are too snug brush against your skin repeatedly and cause an inflammation in the area. Since the proportions of standard shoes may not necessarily match your foot, you may even get a shoe bite after wearing the size that is right for you.
