The bottom is the soul of running shoes
scientific and technological progress so far, any subject is subdivided, any subdivision has professional research results. Now more and more people love sports, sports shoes into everyone's life necessities, sports shoes to sports wear shoes, generally refers to the table tennis shoes, indoor exercise foot does not use too much strength sport wear. Shoes for casual sports, too.
So, if you intend to stick to a sport for a long time, such as running, playing basketball, playing soccer, you need to choose professional shoes for these sports, running naturally requires a pair of professional running shoes.
running shoes are roughly divided into three parts: the outsole, the midsole, and the upper part.
The upper part of the
refers mainly to the upper part of the insole above. Outsole, or outsole, with the bottom of the shoe touching the ground. The midsole is between the outsole and insole. It is the higher part of the three part, and the thickness is about 1-2cm. The action is to cushion the vibration from the ground. When running, the impact of the ground on the body can reach about 8 times walking. As a result, various techniques are applied to the midsole. Most brands use foam rubber such as EVA or PU, in addition to brand patents.
if the sole is the core, in the end is the running of the basic spirit, each brand has its own patented technology alone, but in general, divided into physical deformation, air cushion, cushioning foaming material, this kind of rubber shock.
air cushion slow vibration is a kind of technology that uses the compression of air cushion to absorb shock and then achieve the effect of shock mitigation. It is divided into Air, Max and Zoom. Air cushion technology Air uses standard Max, with a soft feel hard, suitable for large weight people. Zoom is 10 years ago technology, more than ordinary air cushion bombs, soft and hard moderate, landing when not only feel the buffer, and there is a strong reaction, is the so-called rebound feeling, suitable for running more knees will sour people.
technology is through the physical deformation of rigid material in the bottom of the deformation and rebound to do absorb shock and give recoil, such hard foot sole, the need for support or strength better, on behalf of shox, bounce, "arc" technology.
foaming material is now quite rare material, light weight, soft and elastic feeling, the disadvantage is to wear for a long time will be crushed, durability is not good, suitable for the pursuit of "soft" and the soles of shoes can change to wear some people.
cushioning rubber is some professional running shoes commonly used techniques, such as gel, adiprine+, cellular sole technology, such shoes are usually very suitable for running, the technology is mature, but the drawback is that it looks very professional, not suitable for daily use and collocation.
EVA, PU class of professional terms of foam rubber, sounding both familiar and unfamiliar, for non professional we might seem very abstract, next, we focus on not to introduce all kinds of high-tech content is two in the bottom, change >
