TECHNICAL FIELD
[0001] The utility model relates to the technical field of shoe sole, concretely is superlight shock attenuation EVA shoe sole. BACKGROUND
[0002] With the improvement of living standards, fitness is more and more popular among the public, and people's requirements for the functionality of sports shoes are also increasing. As a key component of sports shoes, the shoe sole needs to have important properties such as shock attenuation, stability and flexibility. Currently, common sports shoe soles are mostly made by adjusting the formula of foaming material, production temperature and molding time to achieve different sports performance. However, this method has complicated production procedures and poor superlight and shock attenuation effect. In this context, superlight shock attenuation EVA shoe sole emerges as the times require. EVA (ethylene-vinyl acetate copolymer) material has good softness, rubber-like elasticity, high resilience and tensile strength, excellent shock attenuation and buffering performance, light weight, and also has many advantages such as heat insulation, waterproofness, corrosion resistance, antibacterial and non-toxicity. However, the traditional EVA shoe sole still has room for improvement in the comprehensive performance of superlight and shock attenuation. In order to meet the market demand for shoe soles with superlight and high-efficiency shock attenuation functions, the research and development of superlight shock attenuation EVA shoe sole focuses on optimizing the composition and ratio of raw materials, such as adding specific polystyrene butadiene copolymer, foaming agent and filler, and cooperating with advanced preparation process, to improve the foaming rate, reduce the density of the shoe sole to less than 0.1g / cm³, and enhance its shock attenuation performance, providing consumers with a better wearing experience.
[0003] Application No. CN201820393134.8 discloses a superlight multi-color EVA foaming shoe sole, which includes first and second foaming bodies with different colors.

A fixing part is arranged between each first hollow part and extends downward. A plurality of fixed ribs are arranged in the second foaming body, and a second hollow part is formed between each two fixed ribs. The fixing part is accommodated in the second hollow part, and the fixing part and the fixed rib are seamlessly connected by foaming. The plurality of first and second hollow parts can effectively reduce the overall weight of the shoe sole, making the shoe sole more lightweight. The connection between the first fixing part and the fixed rib provides the shoe sole with good shock attenuation effect. The fixing part on the first hollow part forms a plurality of ventilation holes, which can enhance the ventilation performance of the shoe sole. However, the device cannot be adjusted correspondingly when used in different scenes, which limits the use of the device. UTILITY MODEL CONTENTS
