1. Shoe upper fabric: lightweight and breathable. With breathability as the goal, single yarn weaving directly forms the upper structure, and the weight of a single upper can be controlled at about 20-30g, greatly reducing the overall shoe weight. 2. The weaving density is adjusted according to the stress area of the foot, and there are small air holes between the threads, making it less prone to stuffiness when worn for a long time 3. The tongue and body of the shoe are woven together to avoid traditional tongue displacement and friction on the instep; The shoe mouth is made of elastic yarn, which enhances ankle stability without strangling the foot, supports quick adjustment of elasticity, adapts to different foot types. 4. The rebound holes on the sole are created by combining hollow holes inside the midsole with elastic materials. The midsole is not a solid foam body, but is composed of multiple independent hollow elastic modules, which are usually made of lightweight and high elasticity materials such as EVA. 5.
