What is meant by the term supination resistance?

The foot is a masterpiece of design. 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 in order that we are able to walk, run and carry out a whole variety of actions. The foot is a perfectly tuned biomechanical masterpiece as it must co-ordinate all those functional structures in order that it can function effectively and effortlessly to carry out those activities. The foot did evolve to have those characteristics on a soft ground rather than wearing footwear, so a number of defects possibly crept in as feet was put into footwear and it was forced to walk and run on the hard cement surfaces. Small flaws which were not previously an issue began to show up in those shoes and on those hard surfaces. It is this that is to blame for so many of the problems that health professionals see in the foot nowadays.

For example, one of those problems is a idea referred to as supination resistance. This is thought of as the force that's needed to lift the arch of the foot. If this force is higher, then the muscles and tendons must work harder and the ligaments have more stress on them. This can lead to pain in those structures and the development of a progressive flat foot. If that force is large, walking and running also requires more energy and can be really tireing. If that supination resistance force is too low, then it will be an easy task to raise the arch of the foot. This will result in more ankle sprains because it is so easy to tip the foot over to cause that. From this it ought to be obvious that a fine balance is required between excessive and too low amounts of force which is a good illustration of just what an engineering masterpiece the foot is and just how simple it is for something to go wrong.
