What type of wear pattern is most commonly associated with excessive supination?

The correct answer highlights that a wear pattern associated with excessive supination typically shows significant wear on the outer edges of the shoe. Supination, also known as underpronation, occurs when the foot rolls outward during walking or running. This biomechanical condition leads to uneven weight distribution on the foot, placing more force on the lateral (outer) side.

As a result, the outer edges of the shoe's sole experience heightened impact, causing them to wear down more rapidly compared to other areas of the shoe. This pattern is particularly important to recognize, as it helps in determining the appropriate footwear or adjustments needed for individuals who exhibit this tendency during their gait.

In contrast, other wear patterns would indicate different biomechanics. For instance, even wear may suggest a neutral gait, while wear on the medial side generally points to overpronation. Heavy wear in the heel area often suggests a heel striking gait, which is not typically associated with supination. Understanding these patterns is crucial for making informed decisions about therapeutic footwear that offers the necessary support.
