In the past two months, Ms. Zhao often felt pain in her left ankle, especially after standing for a long time or walking for a long time, with severe pain in her heel. She rested at home, applied creams and took oral pain medication, but there was no significant improvement. Recently, she came to the orthopedic outpatient clinic of the hospital for consultation. Ms. Zhao’s left ankle was not swollen, and there was pressure pain in the inner ankle. MRI examination showed an exudative lesion in her left tibial tendon, which was considered as “left posterior tibial tendonitis”. The patient had no history of trauma, and the “left posterior tibial tendonitis” was related to Ms. Zhao’s preference for snow boots. Like Ms. Zhao wear snow boots to foot disease, not a few people. The appearance of snow boots is lovely and loved by fashionable people, but its structure does not meet the requirements of human mechanics. The stress point of the human foot is the first metatarsal head, the fifth metatarsal head and the heel of the triangle of stability, and the arch is to make gravity from the ankle joint through the talus bone forward to the metatarsal head, backward to the heel bone, to ensure the stability of the sole support when upright, in the body jump or landing from a height, the arch elasticity plays an important role in cushioning shock, in walking, especially long-distance trekking, the elasticity of the arch on the The rhythm between the body’s gravity and ground rebound force has a buffering effect, and also protects the blood vessels and nerves on the bottom of the foot from compression and other effects. The flat bottom and wide design of snow boots make the arch lose its cushioning effect. Wearing a long time walking or standing, tendons and the sole of the foot fascia does not get sufficient rest, there will be swelling and pain on the surface of the foot, walking difficulties. In the long run, the tendons and fascia of the foot are strained, which can easily lead to tendonitis and plantar fasciitis. Parents should not give children and adolescents in the growth period to wear snow boots, so as not to affect bone development. The internal design of snow boots is more fat, while the fur support is not enough, the foot is easy to slide back and forth in the shoe, every step to fight the slip forward, it is likely to cause foot pain because of foot tension, more likely to make the ankle, knee and back joints are worn, walking the formation of the “inner eight”; snow boots soles are too flat, aggravating the Snow boots are too flat, increasing the burden on the arch of the foot, long-term wear tired feet, may lead to flat feet. The flat feet crowd, careful to wear snow boots flat feet is already easy to foot fatigue, if the sole is flat and soft, no hard in the body to fully support the arch, more likely to trigger the arch and calf fatigue secondary injury. Older people, should not wear snow boots The flat bottom design of snow boots can easily cause the body’s center of gravity to shift back, people want to maintain body balance will subconsciously bend forward, easy to bend over, hunchback, older people wearing long-term, may lead to bone and joint damage, it is best to wear shoes with a slight heel. When women drive, they should not wear snow boots The upper and sole of snow boots are thicker, when driving, will make the feet for the throttle and brake feeling dull, the toe is wide affecting the flexibility of the foot is also easy to get stuck in the clutch, brake or throttle between, bringing safety risks.
