GamourDance Tango "The ideal shoe for each foot." 
Choosing the right footwear for each activity and type of tread reduces the risk of injury:
Choose shoes is no easy task. The vast range of brands and models confused from the window of the house of sports. And this is how the choice is likely to be left more or less certain dealer or the advice of not always well trained criterion.
"People choose aesthetic slippers. Sometimes you're lucky, but sometimes not, and choose a shoe that is suitable for tread or their requirements of stability and cushioning," says Gustavo Guerzoni, degree in kinesiology and physical medicine, Nike Running Lab coordinator
"It is essential also to consider the type of use is going to give" added Fernando Colombo, Category Manager of Adidas Runing and the runner's weight, since higher weight, more importantly, have a better cushioning and supports the foot and joints are spared the impact .
Using the wrong shoes for physical activity not only against the expected yield, but increases the risk of injury or, put another way: "There are alterations that can lead to tread suffer an injury, and use the Proper footwear is how to prevent .
Tell me how you stand ...
There are three types of tread: neutral or supinator pronators . Pronation is the inward rotation longitudinal axis of the foot and if it is a natural response of the foot to dissipate the charge to get to each step, there are different degrees of pronation. And with greater severity, the greater the risk of injury.
"90 % of lower limb disorders are related to overpronation, which, in turn, is often associated with flat feet, "says Guerzoni. As people increased body weight, overpronators need a shoe with maximum stability . "
supinating tread, however, is that in which the foot turns outward from its longitudinal axis." This footprint is due generally, a foot with a pronounced bow-Colombo said. This type of foot is very rigid and lacks mobility for cushioning, so you can suffer from various injuries. "
neutral tread, she notes, has no problem to correct. But how about the type of tread own ? While there are signs that might reveal "the pronator shoes deformed on the inside, while the supinator quickly spend its external face, "today there are studies that permit an accurate assessment of the tread.
One of the most modern is the Footscan system. "It consists of a platform with more than 8000 sensors that capture the different pressures made both static and dynamic, during the various phases of the foot during gait," says Guerzoni.
This assessment of the footprint casts, in minutes, valuable information about the type of tread and the existence of alterations of stability in different parts of the foot, while reports on what are the points pressure or hypertension to tread.
All this wealth of information to determine what the most appropriate footwear (for Pronator footsteps, neutral or supine), and also enables the design-in if necessary, of corrective templates, functional or that provide greater comfort.
"Today, a wide variety of materials for the templates, which from a precise diagnosis of the tread can be used to design and customize, providing the necessary orthopedic solution, according to weight and age," says Guerzoni.
" Many elite athletes are already using templates even considered having a normal footing, with the aim of ensuring stability and comfort," he concludes.

is the life of a shoe
On average, a footwear can bring services between 800 and 1200 km, no more.
