Description

Technical Field

[0001] This utility model relates to a foamed shoe sole, specifically a high-elasticity supercritical foamed shoe sole. Background Technology

[0002] In the context of current technology, the sole, as a core component of footwear products, directly affects wearing comfort, athletic performance, and foot health. Traditional sole materials (such as ordinary rubber or EVA) have limitations in absorbing and dispersing impact, which can lead to the soles of the feet bearing greater pressure during exercise or prolonged standing, resulting in foot fatigue or even injury.

[0003] Relying on a single material or structure for cushioning is insufficient to provide good shock absorption, especially in high-intensity sports scenarios, and cannot adequately protect the feet; most traditional shoe sole cushioning materials recover slowly after being subjected to pressure, resulting in insufficient rebound feedback for the wearer during exercise, affecting athletic performance; the material has poor rebound fatigue resistance, and the rebound effect decreases significantly after prolonged use, making the sole prone to losing support and comfort. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a high-elasticity supercritical foamed shoe sole to solve the problems existing in the background art.

[0005] This utility model of a high-elasticity supercritical foamed shoe sole is achieved through the following technical solutions, including: The sole body has a hollow interior forming a receiving cavity, and a cushioning structure is provided inside the receiving cavity; A rebound layer is disposed within the receiving cavity, and the lower part of the rebound layer is in contact with the buffer end of the buffer structure. The insole body is disposed above the rebound layer, and the insole body is bonded and fixed to the rebound layer to prevent the insole body from shifting.

[0006] As a preferred technical solution, the buffer structure includes guide posts and guide holes disposed at the bottom of the rebound layer; The guide post is disposed in the receiving cavity, and a spring hole is formed in the middle of the guide post, and a compression spring is placed in the spring hole; When the rebound layer is placed in the receiving cavity, the guide post is inserted into the guide hole, so that the other end of the compression spring contacts the guide hole; A limiting structure is provided between the receiving cavity of the sole body and the rebound layer, so that the rebound layer is always placed inside the receiving cavity.

[0007] As a preferred technical solution, the limiting structure includes limiting blocks disposed around the sides of the rebound layer and limiting grooves disposed on the sides of the receiving cavity; When the rebound layer is placed in the receiving cavity, the rebound layer is confined within the receiving cavity by the limiting block and the limiting groove.

[0008] As a preferred technical solution, an insole mounting groove is provided above the rebound layer, and the main body of the insole is placed in the insole mounting groove; The insole body is provided with Velcro between itself and the insole mounting groove to facilitate the adhesive installation of the insole body.

[0011] The beneficial effects of this utility model are: This invention features a buffer structure consisting of a guide post, a guide hole, and a compression spring within the receiving cavity. When the sole of the shoe is impacted, the compression spring effectively absorbs and disperses the impact force, significantly improving the cushioning performance of the sole and reducing foot fatigue.

[0012] The guide post of this invention is inserted into the guide hole, which makes the force on the compression spring more stable, avoids the spring from shifting due to uneven force, and further enhances the stability of the buffering effect.

[0013] The rebound layer of this invention is placed inside the receiving cavity and contacts the buffer end of the buffer structure. It can quickly return to its original shape after being compressed, providing excellent rebound performance and improving wearing experience and athletic performance.

[0014] The sole body and rebound layer of this invention are both made of supercritical physical foaming material. With its low density and uniform structure, it has excellent resilience and cushioning performance, ensuring that the sole maintains excellent performance after multiple compressions.
