Back in the day we called them “thongs”. We didn’t know why, but you sure can’t call them that now, they’re just “flip-flops.” And now, foot-care experts are starting to call them bad news for your health. Flip-flops were originally intended for short distances, namely to protect feet from the hot sandy beach. Now they're worn to work, weddings and even the White House. Flip-flops caused a flap in 2005 when members of the Northwestern women's national champion lacrosse team wore them to a visit at the White House.

Flip-flops aren't just hazardous to politicians — they also pose risks for your feet. The floppy footwear, once contained to the beach, can now be spotted year-round and foot specialists say that’s a problem. Most flip-flops offer no arch support and cause people to alter their gait because of the extra work it takes to keep them on. Podiatrists say they see more complaints of heel pain and inflammation during the summer months.

People with perfect feet can wear them with no problems, but anyone with flat feet, high arches, bunions, hammertoes or other foot issues can exacerbate the problems by wearing flip-flops. Flip-flops should also be avoided by anyone with diabetes or circulation problems because symptoms can include a lack of sensation in the feet. Any cuts might not be noticed and can lead to infections. Also, podiatrists say that people with knee, hip or back problems need to wear more supportive shoes so they don't aggravate their injuries. To be safe, it’s recommended you only wear them for short periods and replace them every three to four months.
