The newly released National Foot Health Assessment for 2012 blames flip-flops for a variety of foot pain.
According to the report, the popular but light-weight sandals do not adequately absorb shock when walking on hard surfaces.
Flip-flops can also contribute to tripping, falling, and even serious ankle injuries.
But the report credits flip-flops in some cases . It says they are perfect for walking on hot sandy beaches to avoid blisters.
