Anti-Pronation shoes and insoles
Runners with pronounced pronation tend to put more bodyweight on the inside of their feet and therefore, tend to "crush" the midsole more on the inside. With the passage of time and miles the soft, cushioning midsole gets more squeezed in and the shoes tilt out. This effect becomes an amplifier of the natural pronation of the athlete who, due to the shoes inclined inside, tends to increase the angle of rotation of the foot on the longitudinal axis inwards, becoming, despite himself, an overpronator.
- First, anti-pronation shoes are not "medical devices" that correct one of our defects, but they are shoes that adopt a technological system to remedy one of their defects, that of tilting inside. The old shoes without midsoles, they didn't tilt because they didn't have soft materials that could crush.
- Second and most important consideration; there is no system that, in fact, prevents the foot from continuing to pronate (fortunately) or over-prone inside the shoe.
In these rare cases, the person who can give us a solution is certainly not the shoe manufacturer. The study and knowledge of how we are made and how we really work, i.e. it is by studying the functional anatomy and physiology of our limb-my-fascial systems that we can begin to make reasoning that can untangle us in the world of "false myths" that often fill blogs and magazines.
Biomechanics of foot support
The plantar vault is an architectural ensemble that harmoniously combines all the osteoarticular, ligament and muscular elements of the foot. Thanks to its curvature changes and its elasticity, the vault can adapt to all the roughness of the ground and transmit the stress and weight of the body to the ground in the best mechanical conditions according to the various circumstances.
And here we must necessarily mention and focus on what, more than anything else, is affecting the adaptability of the plantar vault in a negative way.
We are talking about the motor impoverishment we are experiencing in this age of well-being, which has created a new species of the human being: the city man.
The city dweller, in fact, always walks on a smooth, uniform and resistant ground with their feet protected (I would say shielded) by shoes. Their insoles have to make minimum adaptations and the muscles that are the main support, end up atrophying or lose it (use or lose it).
The flat foot is the price to pay for all this civilized progress and the rampant motor impoverishment of children - adolescents of this century. But we are fortunate because we know that we can do much to break this vicious circle created by sedentariness and progress.
We can and must take back our feet and use them for what they can do.
We need to approach a re-education of our foot both by locating attention to the foot itself but also by providing stimulation on a global level to improve our overall human movement. Also, speaking of running, we will work on all those specific exercises to improve the technique. The pronation, in running, is not a static fact but a "rotation" that takes place in each time.
All this will make us talk about pronation only and exclusively for what it really is, which is a physiological and functional event of our foot. Nothing "pathological" or "not physiological" to even must correct with a shoe made specifically for anti-pronation.
