Flip-flops are a must for many people in summer, but, while we enjoy the coolness brought by flip-flops, we must not forget its drawbacks. 1, the damage to the palm of the foot First of all, wear flip-flops “snap” sound so many people feel cool, I do not know, this is at the expense of the heel, flip-flops on the palm of our feet, especially the heel beat too much strength, over time, our heel becomes thick and hard, coupled with the wind and sun, dehydration aging, our heel will eventually be very easy to crack. 2, injury to the foot tendons wearing flip-flops walking, in order to be more firmly clamped shoes, toes will be unconsciously tense for a long time, and curled, this twisted state continues for a long time, the foot tendons strain edema and compression of local nerves. The nerve compression produces pain, which usually occurs early in the morning or at rest after strenuous exercise. In severe cases, nodules appear in the lesion area. 3, lumbar discomfort, internal eight After wearing flip-flops, people tend to unconsciously change their gait and buckle their toes inward to hold the shoes, which will form an internal eight over time. Due to the change of gait, the center of gravity shifts, the spine also needs to adjust to the angle to adapt to this shift, hunchback is inevitable. 4, the arch cushion disappears Normal the bottom of our feet is a certain curvature, the bottom of the foot this curvature can cushion the vibration when walking. However, flip-flops are basically horizontal, not only can not fit the curvature of the sole of the foot, but also can not give the foot enough support. This design is very easy to cause foot pain. 5, the barrier disappears General flip-flops, the surface of the foot is exposed, which gives more opportunities for sharp things such as wooden spikes, sharp stones, the probability of injury can be multiplied. Buckle sandals are much safer compared to this, and do not have to worry about the “flying shoes incident”.
