Most shoe stores have the types of sneakers broken down into sections so that you know where to look. However, there are other things to consider to ensure you put your best foot forward. It's best to try on shoes later on in the day when you're feet are more swollen. Always take the prospective shoe for a test run - walk around in the shoe for at least 10 minutes. When you're trying on shoes, always wear athletic socks like the ones you'll wear when you're engaged in physical activity. You should have about one-half inch of room between the top of the shoe and the tip of your toe. Shoe sizes are ever-changing - so have your foot measured at least twice a year. If you're still unsure if you and the shoe are a perfect fit, consult with a salesperson and determine the shoe best tailored to your needs.
