Simple way to measure the shape of your arch

Your feet wet, step on a piece of paper, if you can barely see the outer edge, then you are a high arch, if you can see the whole foot, the arch of the foot may be flat, ranging between a normal arch. Arch shape and there is no difference between pros and cons, just state your feet when running the force will be different, so you need to select the appropriate shape of the shoe arch. The running shoes of the "function" is a major sports shoe manufacturers strive to study mining content. Good running shoes will take into account biomechanical study. Running shoe design often depends on the material used, sole design, and shape design, shoes for comfort in which the soles and insoles designed running shoes are always the focus of biomechanical research.

Foot - shoe biomechanical modeling, the focus initially is to establish adequate mathematical model of the structure, through the foot bone anatomy ancient mathematical description of calculation to go hard enough, with the development of computer technology, researchers can analyze complex foot structure and function. The researchers also experiment the same time, the pressure sensor pad placed inside the shoe to measure when trying on those running plantar pressure, as the sports shoe design.

Running shoes are often the traditional shoe midsole materials through (midsole) and the sole structure of energy absorption and release at the same time to complete the force of impact suffered foot buffer and protect the foot massage. In other words, heel shock absorption cushioning (shock absorption) and energy feedback efficiency (energy return) is the most important function of sport shoes parameters.

For shock, the general sports shoes companies are in the high end of the use of flexible materials, achieved through the deformation of the buffer material damping. For efficient energy feedback, you need to reduce energy loss. There are several considerations: to reduce the weight of the shoes; enhanced flexibility soles toe bone joint force in order to reduce energy loss; shoe design to enhance the power of the stability of the ankle; teva shoes discount while effectively damping can effectively reduce energy loss.

So often choose running shoes, light weight, high elasticity material, such as air, rubber, etc., as in the end material. Major sports shoe companies on the soles have different designs, such as the Nike Air technology is used in (Nike Air), the pressure of the gas compressed into polyurethane material of the capsule, and now the Lunar series of running shoes were also changed cushioning properties with high rubber; Adidas is some use of viscoelastic foam fitFOAM technical rebound, while others prefer the use of energy feedback POWERBOUNCE technology; Mizuno and unlimited use of ap + wave technology in the bottom and lighter than ordinary rubber more durable; Li Ning Li Ning is using the bow shock system.
