X-rays are an essential way to see the internal alignment of the joints.
This is an extreme example of a problematic foot which is misaligned in the wrong position. This misalignment often causes tearing and straining of the tissues, which leads to pain. When the foot is out of alignment, the body is often out of alignment in other places. Misaligned feet can also cause misalignment in the ankles, knees and hips, potentially causing pain or other issues in other parts of the body as well.
