Depending on the manufacturer, shoe sizes can be different, but most of the time, a B in a woman’s shoe size means a regular width, and a B in a man’s shoe size means a narrow width. An M can also stand for a woman’s shoe with a standard width.
Boot Outfitters says that most men’s regular width shoes are sized with a D or an M. There are many different widths of shoes, from narrow to triple wide. To find the right shoe width, measure the foot at its widest point. It’s best to get your foot measured in a shoe store.
