The American Academy of Orthopaedic Surgeons urges you to follow these fitting facts when you purchase a new pair of shoes. Have both feet measured every time you purchase shoes. Remember, your foot size increases as you get older. Try on both shoes. Fit new shoes to your largest foot.
Most people have one foot larger than the other.
Stand during the fitting process and walk a few steps to make sure the shoes are comfortable. They should not hurt or be too loose. Do not expect shoes to stretch. Your heel should fit snugly in the shoe with no slippage. When the shoe is on your foot, you should be able to freely wiggle all of your toes.
