Features types of soles in sneakers

The first sneakers appeared in the late nineteenth century and have since gone a long history. Now it is not just shoes with studs on the sole, but the most real works of innovative technologies and developments for a more comfortable exercise.

Now, many models of sneakers are a daily option and perfectly cope with their task to create 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 imply stress on the muscles of the legs and back, as well as the inability to practice barefoot. Properly chosen sneakers increase the efficiency and effectiveness of training, as well as reduce the likelihood of injury and the possible consequences of mistakes.

Of great importance is the sole of sneakers, because it is the main load that falls on it. For each sport, different types of soles are preferable, depending on the particular location of the training and the program of training. If you make the wrong choice, it not only minimizes the life of your shoes, but can also cause injuries.

At the sole of sports sneakers multi-layer structure, consisting of an intermediate middle and the immediate outer part in contact with the surfaces of the ground or gym. Each part is different in composition and carries its own special functions.

In sneakers there are several types of sole shape. For a start, it is flat, providing complete contact with the ground. Then the sole, which repeats the anatomy of the foot, and therefore has a small separation-depression between the toe and the heel. On some sneakers, for example, on sneakers jazz shoes, this deepening is as close as possible to the foot, which makes the shoes have a rather unusual concave shape. And, finally, the 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 sneakers are rubber and polyurethane. Polyurethane is flexible, it doesn’t weigh much, it is wear-resistant, it has good thermal insulation and shock absorption performance, but it’s better not to wear shoes with such sole in winter and in ice because of poor adhesion to sliding surfaces. At very low temperatures, this material loses its elasticity altogether, which can lead to damage to the shoe. There are several types of rubber, each of which has its own properties, but in general, this material is resistant to frost, non-slip, durable and stable. Among the cons of a lot of weight, high cost and rapid contamination of the surface.

Not only the outer part of the sole is important, but also the inner, middle layer, as it provides cushioning. Of the materials most used are silicone and silicone based gel. Among their qualities resistance to deformation and temperature drops. The main task of the intermediate sole is to reduce the pressureexerted on legs during exercise. Less common materials are phylo, filait, ethyl vinyl acetate.

A particular thickness of the sole is preferred for its situation and sport. In some sneakers, it will be as thick and wide as possible to ensure adhesion to the surface, whether it be a gym floor or asphalt. Sometimes it is necessary that the shoes on the contrary were light and elastic, and for this, the sole should have a thin one. Fashionable tractor, that is, relief, sole has taken pride of place in sports sneakers. The relief is minimal and frequent or rather tangible, deep, similar to dull teeth.

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

To practice on the dirt surface, for example, in football, you need sneakers with spikes on the sole. Basketball shoes should have good grip and a non-slip sole. In tennis shoes, the sole is thin, with fine relief. In sneakers for fitness, gym, volleyball, futsal, the sole must be elastic, but it is good to support the foot. For dancing it is better to choose shoes with separate soles, so as not to lose the plasticity of the foot.

Special attention is given to winter sports shoes., because it must not only not slide on the surface, but also not to freeze, not to lose its properties. To avoid falls, the sole must be tractor, and the deeper the relief, the better the grip will be provided.
