Description
Technical Field
The invention relates to the technical field of shoe materials, in particular to a high-heeled shoe sole.
Background
The high-heeled shoes are characterized in that the heel parts of the soles are provided with higher heels. The traditional high-heeled shoe structure is characterized in that a steel shank is embedded in a sole, and a heel and the sole are locked together in a mode that one end of a screw is hung on the steel shank to bear force and the other end of the screw tensions the heel.
However, because the heel material is usually a plastic type non-wear-resistant material, the thread used for locking in the heel is easy to wear and deform, once the thread is smooth, the heel can be loosened from the sole, and the accident that a wearer sprains the foot is very easy to cause.
In addition, the steel hook core is made of steel, so that the sole is heavier, and the heavier sole can greatly reduce the wearing and walking comfort of the high-heeled shoe.
Moreover, the manufacturing method of pre-embedding the steel shank and then locking the heel through the screw has multiple steps and complex process, and is difficult to meet the requirement of high-efficiency production.
