At heel strike, how is the foot positioned?

At heel strike, the position of the foot is crucial for understanding the mechanics of gait. During the initial contact phase of walking or running, the foot typically makes contact with the ground in a position of supination. Supination refers to the outward roll of the foot as it strikes the ground, leading to a stable base of support.

In this position, the foot’s arch is maintained and there is some degree of rigidity, which allows for effective shock absorption and prepares the lower limb for the subsequent loading response. This initial supination helps to distribute forces more evenly and provides stability to the ankle and subtalar joints as weight begins to transfer forward.

After heel strike, as the body progresses through the gait cycle, the foot will typically transition into pronation during the loading response phase to absorb impact more effectively. Understanding the dynamics of these phases is essential in evaluating and treating various musculoskeletal conditions related to gait.
