In relation to foot orthotics, what does the term “supination” refer to?

Supination refers to the outward roll of the foot during normal motion, which is essential for understanding the mechanics of the foot during activities such as walking and running. When the foot is in a supinated position, the weight is distributed more towards the outer edges, which can play a crucial role in stabilizing the body during movement.

This term is particularly relevant in orthotic fitting because certain foot conditions or gait abnormalities can lead to excessive supination, sometimes resulting in discomfort or injury. Understanding supination helps orthotic fitters design and recommend devices that can correct or accommodate this motion to promote better foot alignment and overall functionality.

In contrast, the inward roll of the foot is known as pronation, which emphasizes the importance of knowing both movements for effective orthotic intervention. The other options describe different aspects of foot mechanics that do not capture the specific definition of supination.
