7 Ways Your Sneakers Are Ruining Your Workout Routine

They’re tired

You might love your favorite pair of running shoes, but if you’ve had them for years, it’s time to throw them out. “If your sneakers are old and worn out, they could be shifting your weight abnormally, which can lead to injuries not only to your feet, but also to your entire skeleton,” says podiatrist Jacqueline Sutera, DPM, a Vionic Innovation Lab member.
