1, material. Orthopedic insoles are made of polymer materials, which support patients' feet through certain flexibility and strength.
2. shape. Ordinary insoles are flat, while orthopedic insoles are placed at the arch of the foot. The patient's foot shape can be corrected by correcting insoles.
3. unique. Just like myopia needs optometry first, everyone's sole is unique, so orthopedic insoles need to be customized and will not be universal.
Second: precautions for wearing orthopedic insoles.
1, the correct use of biomechanical correction insole treatment is not omnipotent. To get used to it, you can start by wearing 1 hour every day, and then increase it by half an hour every day. Haste makes waste, and you can't wear it when you buy it. This will not only cure the disease but also hurt the foot, because the foot needs to be corrected slowly, and if it is corrected too fast, it may strain the muscles and ligaments.
After trying for four weeks, you should go back and see what needs to be revised. At the same time, it is necessary to cooperate with rehabilitation exercise when wearing insoles.
3. The sole should not be too soft. The insole should be suitable after being put into the shoe, and cannot be propped up by the upper. Shoes should not be too loose to fit. The foot can be stably fixed on the insole. You can't move the insole in your shoes at will.
Third: the daily correction method of flat feet.
Flat foot means that there is no normal arch, or the arch collapses. Normal people's arch height is 14 ~ 18mm, flat feet are below 14mm, and high arch feet are above 18mm. The daily rehabilitation training suggestions for correcting flat feet are as follows:
1, stand up straight, open your feet, grab the ground with your toes, arch your instep, stop and stand up straight, hold the wall with your hands for 10-20 times, breathe evenly, stand upright, turn your feet out, touch the ground with the outer edge of your feet, and stop.
2. Stand up straight, gently hold a fixture with both hands, and stand still with both feet on the round bar on the ground 10 ~ 20 times.
3. Bend down and sit on the ground, raise your feet in turn and do toe-toe stretching exercises 10 ~ 20 times; Indoor barefoot, insist on walking with the forefoot, and usually wear shoes with heels.
