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. 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.
Sizes vary among shoe brands and styles.
Judge a shoe by how it fits on your foot not by the marked size. Try on new shoes at the end of the day. Your feet normally swell and become larger after standing or sitting during the day. A free brochure developed by the Academy provides consumers with helpful tips on how to select shoes for women, children, and athletes.
