Before buying a new pair of shoes, make sure that you try them on later during the day, when your feet are swollen. This will ensure that your footwear will fit properly.
Every year, have your feet measured. Your feet are probably not the same size and may even change in size year after year. Always buy shoes that fit the larger foot and leave 3/8” to ½” of space between your longest toe and the end of the shoe. Make sure that the widest part of your foot sits in the widest part of the shoe.
