What is supination resistance of the foot?

The foot is a marvel of engineering. Each foot has 26 bones, 100’s of ligaments, muscles and tendons. Many of these structures have to function collectively in a really precise way to ensure that we are able to walk, run and carry out a whole variety of activities. The foot is a perfectly tuned biomechanical masterpiece as it has to co-ordinate all those anatomical structures so that it can function properly and effortlessly to perform those actions. The foot did evolve to have those characteristics on a soft ground rather than wearing shoes, so a number of flaws potentially crept in as feet was placed into footwear and was forced to walk and run on the hard concrete surfaces. Small flaws that were not previously a problem began to show up in those shoes and on those hard ground. It is this that is to blame for so many of the problems that health professionals see in the foot nowadays.

By way of example, one of those problems is a notion called supination resistance. This is deemed as the force that's required to raise the arch of the foot. In the event that force is higher, then the muscles and tendons have to work harder and the ligaments have much more strain on them. This can lead to pain in those structures as well as the development of a progressive flat foot. If this force is higher, walking and running also requires more energy and could be really tireing. If that supination resistance force is too low, then it will probably be easy to raise the arch of the foot. This could result in more ankle sprains because it is so easy to tip the foot over to cause that. From this it ought to be clear that a fine balance is necessary between too much and too low amounts of this force which is a great demonstration of precisely what an engineering miracle the foot is and just how easy it is for something to go wrong.
