However, calluses formed by shoes that are too tight or small are usually not as helpful. In fact, once calluses start growing on the feet, because the shoes remain the same size, calluses will continually be growing because of the pressure. This is where the danger lies as corns can be formed from these large calluses and the hard, painful center, can be lodged into the skin.So if you're having problems with calluses are corns the first thing to do is to get a new pair of shoes. Here are a couple tips when you are buying shoes. When you're looking for shoes try to get a round top or square topped shoe, rather than a pointy top shoe. This will allow that the foot to mold into its natural shape rather than be forced into an abnormal position. Another tip is to measure each foot separately when buying shoes. http://tinyurl.com/y4fplfmb
