Why does a flip flop hurt your feet

Many people experience foot pain when wearing flip flops. The main reason for this is that flip flops do not give enough supporting surface to lift shoes, which will lead to muscle pain. In addition, because there is only one herringbone band, the exposed foot area will become larger, which makes the feet vulnerable to injury and sunburn. Sometimes, after a long time of sunburn, it will leave a herringbone shadow, which is very ugly.
