A Surprise Danger to Your Knees and Back

Last spring, I made the mistake of wearing flip-flops on a couple of long walks with my dog. “What does it matter?” I thought. “It’s just an hour walk.” But after doing this a couple of times, I noticed that my knees were sore and my ankles were stiff.

Fortunately, I was bright enough to make the connection between the flip-flops and my discomfort, so I tossed the flip-flops. After switching to a good pair of walking shoes, my joints were no longer sore.

Every summer, thousands of folks slip out of their regular walking shoes and start piling on the miles in flip-flops. As a result, many end up having to visit a doctor.

I asked Dr. Michael Sommers, a chiropractor in Roncasvilles, Toronto, to explain why this innocent-looking footwear can lead to such a dramatic onset of pain.

According to Dr. Sommers, “There is nothing remotely healthy about wearing flip-flops, especially during long walks. They provide little or no support to the ankle and only minimal shock absorption during weight-bearing activity – leading to wear and tear in the joint surfaces of the ankle, knee, and spine. Flip-flops were designed for the beach. That’s really only where they should be worn.”

A study presented at the American College of Sports Medicine found: “When people walk in flip-flops, they alter their gait, which can result in problems and pain from the foot up into the hips and lower back. When subjects wore flip-flops, they took shorter steps and their heels hit the ground with less vertical force than when they wore athletic shoes.”

The researchers concluded that you should wear flip-flops only for a short period of time. So chuck your thong sandals and replace them with walking shoes. Your feet will thank you.
