The ankle is made up of two joints. These joints need to be strong because they support the weight of the entire body. The ankle is one of the most versatile joint complexes in the body. It is built for weight bearing, mobility, adaptability and stability. The foot and ankle allow us to walk, stand, run and jump, and serve as our connection to the ground. The ankle must be able to withstand the stress of our body weight, and also be able to adapt to, and react quickly to changes in environment and walking surface.
