After an admittedly quite long preamble about Nike’s tech, let’s finally talk about shoes.
Scientists, podiatrists, runners and shoe companies are slowly but Nike Roshe Run Dames surely moving away from categorizing their shoes solely based on the degree of pronation support they offer.
Nike is now categorizing their shoes based on the type of run the athlete wants Nike Air Huarache Dames to achieve. The guiding principle is “every run has a purpose”. Some runners want to run at a leisurely pace, maybe high mileage and prefer a shoe that offers comfort, breath-ability and soft cushioning.
Some other runners might prefer running fast and the feeling they want is responsiveness and quick foot turnaround. Other runners instead might be working on improving their Adidas ZX 700 Donna running technique and stride and might be looking for a shoe that allows their feet to move as naturally as possible.
Many runners will be all of these, during different runs and different stages of their training/racing calendar. It is not a matter of how their ankles roll during the Nike Air Force 1 Damen gait – it is a matter of what kind of running they enjoy and what they are trying to achieve. Once that is clear, there will be shoes able to accommodate all kind of over-pronation issues in each of the categories.
The new principle behind the Nike FREE line of running shoes is called “auxetic design”.
When your foot hits the ground, it expands both Nike Air Huarache Dame in length and width. Picture bouncing a ball on the floor: it squeezes and deforms because of the impact, then the opposite happens while it bounces back.
Nike engineers were looking for a way to Nike Air Vapormax Womens design a midsole so that it would expand in both directions during the foot strike. The issue is that most materials, when stretched in one direction, become smaller in the perpendicular direction. Again think of an elastic band. If you pull it to stretch it long, it will most likely become narrower Adidas Gazelle Mujer in the middle.
The auxetic design, characterized by the triangular cuts you see in the picture, allows the sole to do that. A stretch in one direction will equate to a stretch in the other.
