Description

Technical Field

[0001] The utility model relates to the technical field of foamed midsoles, and particularly relates to a high resilience supercritical foamed midsole. Background Art

[0002] The foamed midsole is a material widely used in shoe manufacturing. There are various types of foamed midsole materials. Through different foaming processes, the elasticity and shock absorption performance of the midsole are enhanced to protect the feet and provide a comfortable wearing experience. It is widely used in sports shoes, running shoes and other fields. Therefore, a high resilience supercritical foamed midsole is used.

[0003] For this reason, the patent with the publication number CN216534057U discloses a high-elasticity MD midsole made of EVA foam. A nylon fiber mesh is arranged inside the foamed MD midsole. A buffer and shock absorption component is also arranged inside the foamed MD midsole. A buffer groove is formed on the lower surface of the middle part of the foamed MD midsole. A buffer spring is arranged inside the buffer groove. The upper end of the buffer spring is welded with an upper metal plate, and the lower end of the buffer spring is welded with a lower metal plate. The upper surface of the upper metal plate is fixed on the inner surface of the buffer groove; it is convenient for the foamed MD midsole to be strengthened by the nylon fiber mesh and for the foamed MD midsole to be buffered and shock-absorbed, so as to increase the buffer and shock absorption when the MD midsole is placed in the shoe. At the same time, a buffer groove is formed on the lower surface of the middle part of the foamed MD midsole. A buffer spring is arranged inside the buffer groove. The upper end of the buffer spring is welded with an upper metal plate, the lower end of the buffer spring is welded with a lower metal plate, and the upper metal plate is fixed on the inner surface of the buffer groove.

[0004] Although the above-mentioned high-elasticity MD midsole made of EVA foam is provided with a buffer and shock absorption component inside the foamed MD midsole, which is convenient for buffering and shock-absorbing the foamed MD midsole, it is not resistant to stretching during use, and the midsole is prone to deformation after long-term use, thus making it inconvenient to extend the service life of the midsole. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a high resilience supercritical foamed midsole to solve the defect that the existing high resilience supercritical foamed midsole is not resistant to stretching.

[0006] To solve the above technical problems, the utility model provides the following technical solution: a high resilience supercritical foamed midsole, including a midsole body and a silica gel bump;

[0007] An anti-slip structure is arranged at the bottom end of the midsole body. An anti-stretching structure is bonded to the top end of the midsole body. The anti-stretching structure includes a protective layer, an ACF pad and an anti-stretching layer. The anti-stretching layer is bonded to the top end of the midsole body.

[0014] Preferably, the anti-tensile layer is actually a fiberglass layer, and the protective layer is actually a bamboo charcoal fiber layer. The top end of the protective layer is fixedly connected to the bottom ends of the silica gel bumps and the arch support bumps respectively. Since the protective layer is actually a bamboo charcoal fiber layer, it has various excellent properties such as moisture absorption, air permeability, antibacterial property, and environmental friendliness.

The resilience of the midsole body is effectively enhanced, and the impact force generated during movement and walking can be reduced, protecting the feet and joints.

[0017] The advantages of a high-resilience supercritical foamed midsole provided by the present utility model are as follows:

[0018] By providing an anti-tensile structure, since the protective layer is actually a bamboo charcoal fiber layer, it has various excellent properties such as moisture absorption, air permeability, antibacterial property, and environmental friendliness. Under the action of the protective layer, not only can the comfort and health performance of the midsole body be improved, but also the service life of the midsole body can be extended. Under the action of the ACF pad, excellent shock absorption performance and support force can be provided to protect joint health and reduce sports injuries. At the same time, it has excellent tear resistance.
