Description
Technical Field
The invention relates to a preparation method of a waist pad, in particular to a preparation method and application of a shoe waist pad.
Background
Nowadays, most women like to wear high-heeled shoes due to work needs or women's beauty psychology. The foot is easy to be tired when walking with the high-heeled shoes frequently, and the heel of the high-heeled shoes is rubbed, so that the foot is rubbed by the thumb and the thumb turns outwards, and the foot pain and the lumbago are caused. The reasons for these problems are mostly that the concavity of the bottom center is not enough and the last body is not reasonable when the last is designed. The investigation shows that the high-heeled shoes are not well worn for the following reasons: because the height of the heel is increased, the gravity center of a human body is forward, the bottom center of the waist part of the shoe on the market is not enough in concavity, the stress positions are at the toes and the heel, and the waist part can not well disperse the weight of the human body. Such shoes are unnatural to raise one's head and chest to prevent falling, and when people wear such shoes for a long time, the feet become flat arches, and if serious, surgical correction may be needed. Therefore, a method for reducing the stress on the toes and the heel and the pain of the feet when wearing high-heeled shoes is needed.
