It is found that wearing high heels for a long time will make the muscles and tendons in the back of the calf in a "shortened state", while the muscles in the front of the calf will be lengthened, and the muscle strength around the ankle joint and the stability of the ankle joint will be reduced.
This is because with the increase of wearing high heels, the ankle will gradually adapt to the pressure brought by high heels and gradually reduce muscle contraction.
The decrease of muscle contractility easily leads to the decrease of muscle strength. The decrease of muscle strength around ankle joint will affect the stability of ankle joint.
Health hazards:
First, flat feet:
Wearing high heels for a long time, because the strength of the body is concentrated in some parts of the sole of the foot, rather than evenly distributed on the whole sole, makes the poor walking posture cause foot weakness, and then develops into spastic flat feet.
When walking daily, the human body relies on the big toe root, the little toe root and the heel to support its weight. When wearing high heels, the body weight is basically transferred to the forefoot, which is easy to cause the forefoot to widen and the thumb to bend outward, resulting in "thumb valgus".
The tendon of the arch bridge at the sole of the foot will be pulled. Over time, the tendons will relax, the arch bridge will lose its support and collapse, and the original arch will collapse or disappear, forming flat feet.
Second, paronychia:
If the toenails are repeatedly damaged by external pressure, it is easy to cause toenail ingrowth and bacterial infection to cause paronychia. Wearing high heels for a long time can "attract" onychomycosis through excessive squeezing, friction and oppression of toes by shoes.
Studies have shown that the time spent wearing high heels is directly proportional to the prevalence of onychomycosis, especially the damage to the little toe and thumb. In addition, wearing narrow, high-heeled shoes intensifies the extrusion and friction on the front foot, which is easy to cause corns and calluses.
