Abstract

The invention discloses multipurpose outdoor sports shoes. The sports shoe comprises a composite sole, a composite insole, and a composite vamp cloth. The composite sole is formed by combining an EVA injection molding midsole, a rubber outsole, and an injection molding arch supporting frame in sequence. The composite insole is formed by combining a modified EVA foaming insole and an insole cloth. The composite vamp cloth is formed by a shoe fabric and a shoe lining which are overlaid in sequence. The insole cloth is a blended fabric of bastose and chemical fibers. The shoe fabric is a blended fabric obtained by fibers through blending. The sports shoes have relatively good damping function, and relatively good half sole bending resistance performance and midsole torque resistance function. Through tests, the shoe can bend for 100 thousand times in normal temperature, and has no broken surface and no glue failure. The shoe can bend for 40 thousand times in low temperature of -20 DEG C, and has no broken surface and no glue failure. The sports shoes have relatively good no-skid property, and the sports shoes have relatively good ageing-resistant performance and wash resistance performance.

Description

technical field [0001] The invention relates to a multipurpose outdoor sports shoe. Background technique [0002] Soles should be durable, waterproof and dimensional stable. Different sports also require some specific properties, such as flexibility, stiffness, breathability, thickness / thinness and friction with the ground. When choosing the ideal sole for your athletic shoe, special consideration must be given to the movement of the foot and body, as well as the environment and terrain of the playing field. The thickness and durability of the sole will affect the impact force of the ground on the foot during exercise. SATRA recommends soles for different sports. Running shoe soles are less rigid than climbing soles. Commonly used materials for sports shoe soles are: rubber, plastic, leather, rubber-plastic materials, and polyurethane. The choice of sole material of sports shoes has a certain influence on the hygienic performance of sports shoes. Natural leather has go...
