Description

Technical Field

[0001] This utility model relates to the field of shoe sole shock absorption technology, and in particular to a cushioning and shock-absorbing shoe and its inner core. Background Technology

[0002] Traditional casual shoes and leather shoes suffer from problems such as hard outsoles, weak massage effect, lack of elasticity, poor breathability, inconsistent price and quality, and unsatisfactory wearing experience, failing to meet consumers' demands for ultimate comfort. Furthermore, traditional casual shoes and leather shoes have limited shock absorption, which cannot maintain comfort while standing and walking for extended periods. Traditional shock-absorbing outsoles are costly and complex to manufacture; using popcorn-shaped outsoles or shock-absorbing airbag outsoles in casual leather shoes would incur high mold costs and offer inferior slip resistance compared to rubber or tendon outsoles. Polyurethane materials themselves have poor water resistance, which may affect the lifespan and performance of air cushions in humid environments. Moreover, after prolonged use, polyurethane air cushions may generate excessive heat, becoming less breathable and affecting wearing comfort. In addition, the industry generally suffers from the following pain points: rubber and tendon outsoles in casual leather shoes lack cushioning and shock absorption; the inner core material is hard, offering weak massage effect and a poor wearing experience; foam or latex insoles lack elasticity and lose elasticity after prolonged wear (more than 2 hours); and insoles are not sweat-absorbent and breathable, leading to bacterial growth. Summary of the Invention

[0022] See Figures 1-2 The cushioning and shock-absorbing shoe inner core 100 of this case includes a main body 1, multiple raised massage beads 2 and multiple holes 3; the main body 1 is used to be set at the forefoot position of the midsole 101, and a receiving cavity is formed in the middle of the main body 1; multiple raised massage beads 2 are set in the receiving cavity; multiple holes 3 are set in the receiving cavity.

[0023] In this embodiment, the inner core 100 not only has excellent shock absorption performance, but also good durability and comfort, which can meet the needs of different users.

[0024] During manufacturing, the upper surface of the main body 1 is divided into grids by multiple grid lines. A raised massage bead 2 is set in each grid located in the receiving cavity to increase the pressure buffer. A hole 3 is set at the intersection of each grid line located in the receiving cavity to increase the breathability.

[0025] In this embodiment, the multiple grid lines include multiple parallel lines 10 and multiple perpendicular lines 20. The parallel lines 10 are parallel to each other, and the perpendicular lines 20 are also parallel to each other. The parallel lines 10 and perpendicular lines 20 are perpendicular to each other. Two adjacent parallel lines 10 and two adjacent perpendicular lines 20 form a grid, and a raised massage bead 2 is provided within the grid. The upper surface of the raised massage bead 2 is circular. There is an intersection between the parallel lines 10 and the perpendicular lines 20, and a hole 3 is provided at this intersection, that is, the hole 3 is surrounded by four raised massage beads 2.

[0026] See Figures 3-5 This invention relates to a cushioning and shock-absorbing shoe, comprising a cushioning and shock-absorbing shoe inner core 100, a midsole 101, an outsole 103, a high-elastic blue window pad core 102, a high-elastic thickened insole 104, and an upper 105. The midsole 101 has an inner core groove at the forefoot position, within which the cushioning and shock-absorbing shoe inner core 100 is disposed. The outsole 103, the midsole 101 including the inner core 100, the high-elastic blue window pad core 102, and the high-elastic thickened insole 104 are layered sequentially from bottom to top.

[0027] In this embodiment, a wrap-around shoe process (using soft midsole fabric instead of rigid midsole paper) is employed. A polyurethane shock-absorbing core 100 is inserted by hollowing out the forefoot area of ​​the midsole 101 fabric. A high-elastic blue window insole core 102 can be placed in both the forefoot and heel. The high-elastic blue window insole core 102 and the high-elastic thickened insole 104 can also be integrated into a single high-elastic thickened blue window insole. The surface of the high-elastic thickened blue window insole has multiple ventilation holes, and perforations on the insole further enhance breathability. This provides customers with a lighter, softer, more comfortable, breathable, and effectively cushioned leather shoe. The forefoot polyurethane shock-absorbing core 100 aims to absorb and disperse the impact generated during walking by utilizing the elastic properties of polyurethane material, combined with the patented blue window insole, reducing pressure on the feet and improving comfort and athletic performance.

[0028] The core principle of the forefoot polyurethane shock-absorbing core 100 is based on the characteristics of polyurethane, a high-molecular synthetic material. Polyurethane is formed by the reaction of raw materials such as oligomeric polyols, polyisocyanates, and chain extenders, and possesses various functional groups, such as urethane groups, ester groups, and ether groups. These characteristics give polyurethane (PU) materials excellent wear resistance and elasticity. During the manufacturing process, polyurethane materials are processed into PU pad cores with specific shapes and properties through specific processes (such as foam molding). This PU pad core is not only lightweight and soft, but also provides durable support and cushioning, effectively reducing foot fatigue. In summary, the utility model concept of the forefoot PU-coated shock-absorbing pad core is based on the excellent properties of polyurethane (PU) materials. Through specific manufacturing processes and shape design, a lightweight, soft, comfortable, and effectively shock-absorbing PU pad core material is achieved.

[0029] The forefoot polyurethane shock-absorbing core 100 is mainly used in footwear such as athletic shoes and casual shoes. It aims to absorb and disperse the impact force generated during running or walking through the elastic properties of polyurethane material, reducing pressure on the feet and improving comfort and athletic performance. This technical solution details the design, manufacturing, and optimization process of the forefoot polyurethane shock-absorbing core 100.

[0030] The combination of a 100-type polyurethane shock-absorbing core in the forefoot and a patented thickened insole with a blue window core solves the problems of insufficient shock absorption, poor water resistance, high internal heat generation, and foot fatigue during walking in traditional rubber outsoles of women's casual leather shoes. By optimizing the polyurethane material formula and structural design, a more efficient shock absorption effect is achieved in the finished shoe, while simultaneously improving water resistance, reducing internal heat generation, lowering costs, and simplifying the production process. Furthermore, this design also focuses on wearing comfort, ensuring a good balance between shock absorption performance and comfort to meet the stringent requirements for shock absorption in casual leather shoes.

[0031] This project aims to address innovative shock absorption technology in shoe soles, distinct from that used in athletic shoes. It achieves cushioning and shock absorption by combining the 100 material in the insole core with the 101 forefoot massage and shock-absorbing pad in the midsole. Through the use of polyurethane material and innovative structural design, shoes featuring the highly elastic, lightweight, durable, and easy-to-manufacture forefoot shock-absorbing core 100 are produced to meet consumers' higher demands for comfort.

[0032] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
