What does inversion refer to in foot movement?

Inversion refers to the movement of the foot where the sole turns inward toward the midline of the body. This action typically allows for better balance and stability, especially during activities that involve shifting weight or changing direction. It's an important motion in many sports and rehabilitation settings, as it helps maintain proper alignment in the foot and ankle during dynamic movements. Understanding inversion is crucial for assessing foot function and implementing appropriate exercises or treatments for injuries, particularly those that may arise from excessive or improper movement patterns.
