FORT WORTH, Texas -- Warmer weather is here, and many people are trading in their socks and shoes for flip-flops. But doctors say the popular footwear is responsible for a growing epidemic of heel pain.

Flip-flops have no arch support, and the abnormal motion of the foot leads to irritation and heel pain. So what do you do if you don't want to give up those fashionable flip-flops?

"We're really trying to get out the word that this new fashion craze of flip-flops really should be toned down. It's OK to wear them from time to time, but if you're going to wear sandals on a daily basis, it should be something a little more sturdy with a thicker sole and a good arch support in them," said Dr. Marybeth Crane, a podiatrist.

Doctors say if you or your child wear flip-flops and have heel pain for more than seven to 10 days, get back into tennis shoes or sturdy sandals, stretch the foot and rest when you can.

If it doesn't get better in two to three weeks, you should see your doctor to avoid long-term foot problems.
