What is the supination resistance of the foot?

The foot is a marvel of design. Each foot has 26 bones, 100’s of ligaments, muscles and tendons. Most of these components have to function alongside one another in a very precise way in order that we can walk, run and perform a whole variety of actions. The foot is a perfectly tuned biomechanical work of art as it must co-ordinate all of the physiological structures so that it can function properly and effortlessly to undertake those actions. The foot did evolve to acquire those functions on a soft surface rather than wearing shoes, so a number of defects possibly crept in as feet was put into footwear and was forced to walk and run on the hard cement surfaces. Small weaknesses that were not previously an issue began to show up in those shoes and on those hard ground. It is this which is responsible for so many of the problems that health professionals see in the foot nowadays.

As an example, one of those issues is a idea referred to as supination resistance. This is viewed as the force that is required to raise the arch of the foot. If that force is higher, then the muscles and tendons have to work harder and the ligaments have a lot more stress on them. This may lead to pain in those structures and also the development of a progressive flat foot. If this force is large, running and walking also needs more energy and could be very tireing. If that supination resistance force is too low, then it is going to be an easy task to raise the arch of the foot. This can result in more ankle sprains because it is very easy to tip the foot over to cause that. From this it should be obvious that a fine balance is necessary between excessive and too low amounts of force which is a great demonstration of just what an engineering wonder the foot is and just how simple it is for something to go wrong.
