2, it is very easy to destroy the neck of the boot, because the position of increasing the insole is the relative height-width ratio of the heel neck, so the foot that can be wrapped up in the neck of the walking boot is much less, so there will be a dragging feeling when walking, and the neck of the boot will be worn out more severely.
3, the big drawback, because casually lifting the insole will not support the foot well, and the foot is originally a parallel road, but the insole will be low and then high, which will cause the forefoot Baidu to be too large, which will have an impact on the foot bones. The design scheme of height-increasing shoes is all based on scientific principles, which is the biggest difference between height-increasing shoes and height-increasing insoles. However, height-increasing shoes can only change your height-width ratio from the visual effect, but can't actually deal with the problem of shortcomings.
Four kinds of pain that may be caused by internal heightening insoles:
1, Foot Pain When walking, each foot has three support points, two for the forefoot and one for the heel. If the height-width ratio is not suitable, the force point of the heel will shift and the net weight of the whole body will be concentrated on the sole and the sole, which will cause the sole and the sole pain.
2, knee pain heel pick up 1 cm, when walking or going up the stairs, the kneecap will instinctively bend. Generally speaking, if the height of the insole exceeds 5 cm, the kneecap will bear three times the working pressure of the rest weight, which is equivalent to tying a heavy lead piece to the knee joint. If you wear that kind of internal elevation for a long time before 15 years old, it will cause problems such as kneecap protrusion, making the knee joint not straight and foot deformation.
3. After the low back pain is put on, the human body will lean forward in order to maintain stability. The lumbar muscles will only be tightened all day, which will cause lumbar bone pain and lumbar muscle strain after a long time. Therefore, it is definitely not suitable for the increase in wearing during menstruation and fitness exercise.
4, headache, headache, is one of the symptoms of high-heeled shoes syndrome. If the internal height is changed, the recoil of the road surface on the body will still repeat the same trick. When walking, every recoil that should be digested and absorbed by the foot plate will fluctuate in the head. The longer you wear shoes with internal height, the more obvious the headache will be.
