Quick Tip: Keep Your Feet Healthy This Summer

How do you know when it’s time to retire those hiking boots?

Take a look at your soles, says Colleen Schwartz, DPM, a podiatrist and pilates instructor in Pleasanton, California. If the tread is smooth or noticeably worn, it may indicate that the materials in the insole and midsole have exceeded their useful life and could be causing strain in the arch, inflammation, and even shin splints. Or follow the same guidelines established for athletic shoes—after 350 to 500 miles, you can safely retire those dawgs.
