Lateral sway and spirals in movement are defined by ankle mechanics. Lateral sway involves a greater range of motion, allowing the ankle to complete larger circular patterns, while spirals have a tighter range, focusing on smaller, more controlled circles. Both concepts are connected to achieving proper ankle set. The use of asymmetrical insoles offers an optional layer to support either lateral sway or spiral mechanics, enhancing foot and ankle function.
