Sports shoes soles and uppers of material development

Footwear is not only required to withstand the various stresses on the Movement, but also for comfort, so different professional sports shoes on the soles and uppers are different materials. Sports shoes sports shoes with the material requirements, including a long system of ordinary shoes, short shoes system, tennis shoes, athletic shoes, soccer shoes and other general sports training and physical exercise when wearing shoes. Sports Cheap Air Shoes uppers quite broad, laminated soft, breathable upper Scuff; its external end has a good slip resistance, high elasticity, resistance to flexing and abrasion, and wear comfortable and light. From the technical requirements for the structural design of sports shoes should Genjiao should be beneficial to the protection of the feet when vigorous exercise and human support, they should not wear the skin or aggravate foot injury foot fatigue. Therefore, the first timber for shoes required no harmful substances, and certain anti-static capability; to be a good permeability, permeability and moisture absorption, to ensure that sweat can fully discharge in order to avoid foot skin; should variability with better ammunition to expand with the foot and body movement after another restitution; requires a certain degree of water resistance, heat resistance, cold hardiness, mildew resistance and ultraviolet fire; to have to withstand repeated bending capacity and excellent wear resistance; can tolerate a certain temperature and the necessary shape and adhesion to meet the requirements of a variety of manufacturing processes. Comfortable and durable materials, is working to develop natural cow leather, especially leather, is the largest use of upper materials. The advantages of natural leather-like layer of fibrous network of the interlacing structure formed body so that it can breathe. Its soft warm feel more other materials can not be replaced. However, the permeability of natural leather comes from its open structure, high water absorption, therefore, is not waterproof. Therefore, when faced with some high boots rain, soon will be wet. The face of complex and harsh outdoor conditions, more and more emphasis on R & D personnel in the allocation of water and water-proof leather features material from their skin began to improve processing performance. 3M Company developed the thinking Gao Jie (SCOTCHGARD) leather protector is a major breakthrough, leather and appropriate by the thought process purity and treatment, the leather has allocated water, oil and dust effects, not easily become dirty, stains can be avoided contaminated leather, while also maintaining the original feel, breathability, appearance and odor. In addition, BAYER and BASF and other large chemical group is also working to develop leather protecting agent, and has achieved good results. When the rain water poured into a call when the effect of cow leather, rain will present upper left-shaped ball, only a very small part will be attached to the upper. But the shoes are waterproof material not only by itself, apart from shoes to some water seepage material, there are sewing needle, upper and sole combination of parts. A waterproof breathable film with the inventions of this has been applied, the kind of film is less than the pore water molecules, greater than the air molecules will be the pre-posted a hole in these parts, the prepared feet moisture within the shoe Keshi penetrate into shoes, the rain outside the shoes can not invade the shoes in order to achieve a better effect of waterproof breathable. However, with the use of time, the skin surface of the water allocation of the performance will be weakened and eventually will lose the effectiveness of allocated water. A kind of micro fiber with PU coating on the substrate made of artificial leather, its texture and permeability have been competing over looks with leather and footwear industry are the growing number of applications. In addition, people like to wear cloth shoes a long time, which the fabric can be nylon cloth, mesh cloth, canvas, in order to overcome the shortcomings of its poor water resistance, and technical personnel management with DuPont Teflon outer canvas upper, it features a water allocation . The bottom of the pieces of material the most attention to the mountain range, ski, rock climbing series, Beach series, running series of outdoor shoes, not only for the surface material to help high demand, but also very demanding on the bottom of the piece. Such as high altitude boots the soles of boots usually bigger super durable Vibram rubber bottom, lined with carbon fiber, has a strong impact resistance, can be fitted crampons, boots to help design more than 20cm, with hard plastic boots facial resin or thicker leather, sheepskin sewn, lined with warm shoe covers, adapt to the complex bad snow, ice, rock mixed terrain, in order to effectively protect the feet. Some common outdoor shoes or SympaTex for Gore Tex lining, the intervening insulation layer to enhance the waterproof effect. Professional brand and the bottom end of the large room is also designed nylon board support to enhance the hardness of the shoe, can effectively prevent the sole deformation, and increase impact resistance. Often used in upper layer of medium thickness head cowhide, sheepskin or leather mix upper, leather face some super-resistant Cordura help choose fabrics Du, mountain range, compared to the lighter and more flexible is better. In order to solve the water problem, most of the models used Gore Tex material used in the lining, and some oil waterproof leather, these shoes can be less water in the ankle or walking in the rain.
