Shoes are supposed to fit properly, or your feet will hurt. Ask any Doctor. Ask a shoe company and they will tell you that the laws of physics are suspended when buying shoes and that you can solve a problem of a shoe being to wide by adding an insole. Unfortunately for them the laws of physics always win, and you cannot solve a problem of wrong width by decreasing height. Business has decided that with the economic down turn that we all are the same size 'D' or as they like to call it 'normal' width. So the other 20% of the world that cannot wear a D is abnormal. The only thing abnormal is that the think we will fall for it. Some of us are not stupid, and will continue to demand proper fitting shoes. Have hope that someone in the business will read this and realize that they can make money by being the first back in the business of making shoes that fit.

'D' and/or 'M' is the shoe size width measurement, and indicates a medium or standard width. Sometimes the shoe width size will be indicated with only a 'D' or 'M.' Furthermore, a 'C' width would be narrow width, an 'E' width indicates a wide width, and an 'EE' width would be extra-wide. If you're seeking detailed information on the exact width measurements, measured in inches, there should be some U.S. shoe size width charts available on the internet, found using the keywords, "US shoe size width chart."
