Studies show that a pair of shoes well chosen reduces in 50% the opportunity of injuries, most of them caused by lack of flexibility, cushioning, stability and / or biomechanical control.
Under Pronation Running Shoe
The forces of impact caused in the race are between 3 to 5 times the body weight of the runner. If the shoe has good impact cushioning capacity, most of these impacts are scattered by the midsole.
Flexibility is necessary because of the high degree of repetition of foot movements during the race.
The stability and / or biomechanical operate are also vital. All runners have prone or supine problems in dissimilar degrees. Shoes with sufficient stability help compensate these needs.
Biomechanical operate and / or stability can be obtained straight through the molded midsole, devices to avoid or cut pronation and duplicate density midsoles with the right shape and construction measures.
The chamber is of greatest importance, a shoe may be technically evolved but if it doesn't accommodates well it cannot be used. A running shoe should be tight to the ankle and instep, but should have sufficient room in the toes so that they move freely.
The lifetime of running shoes is about 500 to 800 km, as the insole should be changed at least once during the life of the shoe.
Competition Shoes
Shoes that weigh less than 250g are determined contentious (note that the weight is measured on a shoe size 9 (about 42 Eur/40 Brazil) scale American male and a size 6 (about 36 Eur/34 Brazil) in scale female).
The shoes of competition are divided into two families
Distances up to half marathon
The shoes of competition for up to half marathon distances, are extremely light, so having less material in its constitution, and therefore offering an extremely low weight at the charge of support, stability and cushioning on impact.
Who should use these shoes
Light weighted runners and biomechanically efficient, for short races (up to half marathon) to a contentious level.
Marathon Distances
The competition shoes for distances up to marathon are extremely light, so having less material in its constitution, and therefore offer an extremely low weight at the charge of support, stability and cushioning of impacts, some shoes of this family have very similar characteristics to the execution shoes family.
Who should use these shoes
Light weighted runners and biomechanically efficient, for runs of all distances up to marathon at a contentious level.
The differentiating factor is essentially the weight, up to 200g can be assumed that the shoe is for up to half marathon distances, up to 250g will be a marathon distances shoe.
