Flip-flops drag on 
 
 
China's traditional Chinese medicine to 

    There is a saying "flip-flops, drag people." Seemingly in jest, flip-flops do have many disadvantages, the influence is healthy.
 
    The bad one: foot table unprotected, vulnerable to injury. The flip-flops, mostly bare feet, while walking along the gravel road, the muddy road, unable to protect the foot, it is easy to scratch, cut, stab, etc. At the same time, the being slapped at the back of the shoes on feet, make skin hardens.
 
    Harm 2: feet no arch support, muscle tendon strain. Normal feet have certain radian, can help buffer when walking, and flip-flops cannot suit the soles radian in walk, also can't give foot enough retainer. Only two thin straps flip-flops, or only a v-shaped belt across the toes. In order to pick up the shoes more firmly, toes long unconsciously taut, and curled up shaped to "grab" the soles. The distorted state last for a long time, can lead to tendon strain under the toes, causing heel pain, arch, and toes, appear even nerve inflammation.
 
    Harm 3: induce hip and waist pain, "eight". Flip-flops, often will not consciously change gait, frequency faster, smaller steps, walk this way is easy to cause the pain in other parts of the body. Flip-flops to wear very no response, so in order to avoid the embarrassment of shoes with feet flying, people often deliberately reduced pace, and turn the inside of the ankle to "live" shoes. Body center of gravity forward, knee bends naturally, lumbar spine bending will follow, time is long, will not only make the pace of "eight", knee and spinal pain, and even brings the problems such as sciatica.
