In fact, podiatrists say that summer's favorite footwear is responsible for more health problems than any other type of shoes, even high heels.
With the average American taking between 10,000 and 20,000 steps each day, the small changes in one's gait can add up to serious injury.
"The major shock absorption occurs back on the heel, and if the surface between the heel and the ground is not supported it does not allow the heel to absorb shock as well as it should. Which means the foot works harder than it should and people tend to develop overuse injuries such as tendonitis, or in this case, lower leg, knee, hip and back problems," explained Dr. Rock Positano from Hospital for Special Surgery in New York.

"Look, this is not an attack on a flip-flop or a flip-flop like shoe. Once again, it has to do with when you wear the flip-flop. If it's for hanging out around the swimming pool, or hanging out around the beach, or hanging out with your friends, they're fine," he said.
