Boot sole It is the cornerstone of a pair of boots and the foundation of all the functions of a pair of shoes. All manufacturers invest a lot of money. Development Develop excellent boot material. The classification of mountaineering boots is also based on different types of boots. Material Science Divided

The first thing to consider is the matching of autumn boots, the matching of girls' boots, the matching of boots with short skirts, and the matching of men's boots. In the final analysis, boots are the foundation of a pair of boots and the foundation of all the functions of a pair of shoes. All manufacturers have invested a lot of money in developing and developing excellent boots materials. The classification of mountaineering boots is also classified according to different types of boots materials, so as to adapt to all kinds of geographical conditions, to reduce the physical exertion of climbers, and to protect the personal safety of climbers. The bottom of the boot includes the insole and the outsole. The inner bottom directly contacts the footboard of the human body, usually made of soft nylon material. The shape design is based on the characteristics of the foot type of the person, and some of them are added with a thin steel plate and coated with a kind of anticorrosive coating. Different types of climbing boots have different interior design and materials, and their comfort is also different. Apart from the bottom, some alpine climbing boots also have a middle sole, which is made of nylon synthetic materials, which contains shockproof buffer microporous structure. Outsole Direct contact with the ground is usually made of synthetic rubber material. Different manufacturers use different synthetic materials, but the purpose is to effectively protect the toe, increase the comfort, while the heel is low, light, skid resistant, and the bottom surface has a groove to prevent slipping. At present, the medium and high class mountaineering boots are made of sole shoes of Italy Vibram company. Vibram soles are made of hard synthetic rubber materials, and their biggest feature is anti skid. Rubber itself is a kind of skid resistant material, then according to the engineering raw materials, forming irregular shape, producing uneven surface, can produce greater friction. Different types of mountaineering boots are made of different types of Vibram, such as the bottom of the mountain boots with claw grooves, which can be directly fitted with claws, and Vibram bottom with shock proof micropores, high strength carbon fiber and so on.
