Shop at the end of the day when your feet are slightly swollen to get a good fit.
Try on shoes with the socks you will wear when walking. If you use an orthotic, bring that to the store when you try on shoes as well.
Have your feet measured standing up and fit your shoes to the larger of your two feet.
Be sure there is enough room in the toe box for your toes to wiggle and about a half inch between your toes and the end of the shoe.
Take time when shopping to try on different brands and walk around the store in each pair. Be sure to walk on a hard surface, not just on carpeting. Let your foot be the guide to the fit, not the shoe size or style.
Look for lightweight, breathable materials for greater comfort.
Run your hand all over and inside the shoes to feel for any seams or catches that might irritate your foot.
Choose shoes that lace for better foot stability and control.
Make sure your heel fits snugly and does not slip out of the shoe.
Consider buying two pairs and rotating your wear to give each pair time to breath between runs and extend the life of each pair.
*****Replace running or jogging shoes twice a year or about every 400 miles.******
