When choosing to buy a new shoe, you must take into consideration the shape and size of your foot. Try on shoes at the end of the day instead of early in the morning. As the day goes on, our feet swell as we walk, so a pair of heels that fit just right during brunch might turn painful and restrictive later in the day. Finally, make sure you give any prospective shoe purchase a test before you go through with buying them. A shoe can be in your size but reveal all sorts of problems with fit once you start walking in them. To ensure that they’ll be comfortable once worn, try moving your foot around in the shoe to see if there are any bits such as seams or tags that might poke or rub against your heel.
