Sneakers have always been! It's a bold statement at first glance seems moot. Robotics shares his opinions and ideas on the topic at hand. In fact, the assertion that the sneakers in the broadest sense has always been difficult to challenge, we are talking about adaptations for running, created from improvised materials. A run was also always the case. Ancient people often had to catch up and even more frequently to escape. They could not help but notice how vulnerable bare feet. At every step of waiting for danger in the form of sharp stones, Poisonous snakes and invisible potholes.
To protect the feet, people used tree bark, animal skins, palm leaves. Evil poor, they managed to create something very remotely resembling modern universal athletic shoes. It is universal, that is, a sports shoe, which would be old enough for all occasions, when required to run, jump, climb the hill, climb trees, move gravity and so on. Universal shoes still exist. For tens of thousands of years they have improved to such an extent that the ordinary athletic shoes have become a complex technique with a mini-computer, and the little motor cable system.
The price of these devices seems fantastic, even in comparison with the best models of sport shoes from leading manufacturers. But it is – an extreme, which will not be saved in the production of things designed for a wide demand. Manufacturers of athletic shoes are often trying to catch two rabbits at once, or to sit on two chairs: to please the fashion trends in clothing and footwear for all and please, along with the request professional athletes. Creating new models, such as running shoes, they are more concerned about the abrupt appearance than about the functionality of a professional shoe for running. But running has always been. And a long time ago it is clear that stops working during the run is not quite as during walking. Human feet are divided into three groups according to the nature of the arch: giperpronatory (excessive flattening; joints while running and overwork lose their stability), gipopronatory (insufficient flattening of the foot badly softens the load) and neutral pronator (the norm). For the latter group are suitable stabilizing shoe type (stability), for the first – controlling (control) jogging shoes – the most control pronation, the second – the neutral absorbing (neutral) sports shoes, promotes a more natural movement of the legs. To set up your group, you have to pass a simple 'wet' test: take a sheet of thick paper, put it on the floor, soaking his bare feet, stand on a piece about half a minute, then get off the sheet and a pencil to outline the boundaries of wet spots. Most of the problems associated with the character of the arch, disappears in the case of proper running technique – an athlete lands on the front of the foot, holding his leg, slightly bent at the knee joint. That is exactly what did our ancestors, for the simple reason that a child ran barefoot.
