The Soft Material In The Force Prone To Deformation
Germany Bayer MaterialScience Introduces molded polyurethane soles
, lightweight and elegant, transparent color, or black, about 60% lighter than ordinary soles, suitable for the production of sports shoes or safety shoes. Recent years casual shoes sole material the use of natural, environmentally friendly materials (such as grass, hemp, brown, rattan, synthetic materials, etc.), such material has a thin texture, light, wear-resistant, non-slip characteristics. The 5 internal material softness and smoothness footwear internal softness of the material (lining), their comfort is closely related to, the material is more soft, comfortable footwear, the better. This is due to the soft material in the force prone to deformation, and when the deformation to meet the requirements of the foot itself, to feel comfortable.
But it is not the material deformation big shoes on the comfortable, but also has good elastic recovery (ie plastic) material deformation, if the deformation can not be restored, the big difference will lead to a the footwear space within the foot body space, but will with discomfort to the foot. The same is true of the smoothness of footwear materials, smooth footwear internal material can foot feel more comfortable, the internal material is too smooth, people walking on a sloping road, feet in the footwear content easily slide to the lower or skidding. The one hand, due to repeated friction between the foot surface of the skin and footwear materials, resulting in the foot surface skin abrasions; the other hand, it is also because of sideslip to cause foot ankle injury, foot joints hurt, footwear comfort decreased. 6 sole material and structure of the shoe sole material is determined all its features and comfort of the base, including the production of the bottom piece of raw materials used, the thickness of the base member and tread design. Good quality footwear the bottom of the insole material midsole material and insole material should be absorbent, breathable, has better dimensional stability and resistance to flex, so as to give the foot a comfortable environment.
Many research institutions and manufacturers Ministry has invested a lot of manpower, material research and development of high performance shoe materials, such as the soles commonly used raw rubber, PU, ??EVA shock-absorbing material such as step up comfort and smooth; in the bottom part of the universal thinner, so double feet more affixed to increase the walking and driving sensitivity.
Sole design is not too thick, winter wear footwear design thicker bottom type is conducive to isolate the ground moisture, air-conditioning, to maintain the normal temperature of the foot; thick, and also causes the foot to change the feeling on the ground poor, easy to make the center of gravity skew phenomenon of Wei feet. Sole pattern should be designed so as shoes with anti-lateral, longitudinal slip performance. The effect of non-slip soles, people walking elbow soles to increase friction with the ground, with the ground reaction force would feel walking ease; Conversely, difficulty walking, and easy to make legs and body hurt. For example, many in high-end hiking boots are used Italian Vibram soles made of a synthetic rubber material, its biggest feature is skid rubber itself is a
