The foot performs the following functions:
- safe travel, regardless of the surface on which the foot treads;
- control of movement, i.e. the ability to choose and change direction (walk forwards, backwards, sideways);
- Reduction of the load during walking, which falls on the knee, hip joints and spine.
As you can see, foot function is a lot like the wheels on a car, and foot pathology is like driving with a flat tyre. Even if the whole car is working properly you can't drive normally with a flat tyre.
