Features of the types of soles in sneakers

The first sneakers appeared back in the late nineteenth century and have since gone a long history. Now it’s not just shoes with studs on the soles, but the real works of innovative technologies and developments for more comfortable playing sports.

Now many models of sneakers are a daily option and perfectly cope with their task of creating comfort during long walks. However, in the case of serious sports, it is best to purchase specialized shoes. It is of great importance, since many disciplines involve tension on the muscles of the legs and back, as well as the inability to engage in barefoot. Properly selected sneakers increase the efficiency and effectiveness of training, as well as reduce the likelihood of injury and the possible consequences of mistakes.

The sole of the sneakers is of great importance, because it is it that accounts for the main load. For each sport, different types of soles are preferable, depending on the characteristics of the location of the training, the training program. If you make the wrong choice, this will not only minimize the life of the shoes, but can also cause injuries.

The sole of the sports shoes has a multi-layer structure, consisting of an intermediate middle and a direct external part in contact with the surfaces of the ground or the gym. Each part is different in composition and carries its own special functions.

Sneakers have several types of sole shapes. To begin with, it is flat, providing full contact with the ground. Then the sole, which repeats the anatomy of the foot, and therefore having a small separation-deepening between the toe and heel.On some sneakers, for example, on jazz shoes-snickers, this recess is as close as possible to the foot, which is why the shoe has a rather unusual concave shape. And, finally, a recent novelty, the sole for “passive” weight loss is semicircular and round, providing the necessary effect on the muscles of the legs and buttocks during normal walking.

The main materials for creating the sole of the sneakers are rubber and polyurethane. The polyurethane is flexible, does not weigh very much, is wear-resistant, it has good thermal insulation and amortization, but it is better not to wear shoes with such soles in winter and in ice due to poor adhesion to sliding surfaces. At very low temperatures, this material completely loses elasticity, which can lead to damage to the shoes. There are several types of rubber, each of which has its own properties, but in general this material is resistant to frost, does not slip, and is durable and stable. Among the minuses are large weight, high cost and fast surface contamination.

It matters not only the outer part of the sole, but also the inner, middle layer, as it provides cushioning. Of the materials, silicone and silicone-based gel are the most used. Among their qualities are resistance to deformations and temperature changes. The main task of the midsole is to reduce pressureexerted on the legs during exertion. Less common materials are filon, filite, ethyl vinyl acetate.

One or another sole thickness is preferred for your situation and sport. For some sneakers, it will be as thick and wide as possible to provide traction, whether it be the gym floor or asphalt. Sometimes it is necessary that the shoes, on the contrary, be light and elastic, and for this the sole should be thin. Fashionable tractor, that is, embossed, the sole took pride of place in sneakers for sports. The relief is minimal and frequent, or quite noticeable, deep, similar to blunt teeth.

For running in the gym on the treadmill or on even hard asphalt, soft, flat soles are suitable. However, if you prefer to run along a dirt road and land, where it is likely to stumble on sharp stones, glass, step on the roots of trees, then a rigid sole is preferable. In general, when running, it gives priority to the lightness of the product. But for shoes for sports walking, the sole is stiff and corrugated.

For training on a dirt surface, for example, in football, sneakers with spikes on the sole are needed. Basketball sneakers should have good grip and a non-slip sole. Tennis shoes have a thin sole with a small relief. The sneakers for fitness, gym, volleyball, futsal should have elastic soles, but support the foot well. For dancing, it is better to choose shoes with separate soles so as not to lose the plasticity of the foot.

Winter sports shoes deserve special attention., because it should not only not slide on the surface, but also not freeze, not lose its properties. To avoid falls, the sole should be tractor, and the deeper the relief, the better traction will be provided.
