Supination (Underpronation) Explained

In brief: Supination, also called underpronation, is when the foot rolls outward and stays on its outer edge rather than rolling inward to absorb impact. It is less common than overpronation. Cushioned neutral shoes usually suit supinators because the foot does not need added support.

What is supination?

Supination, also known as underpronation, is when the foot does not roll inward enough and instead stays on its outer edge through the stride. Weight is carried along the outside of the foot, and push-off comes more from the smaller toes. It is the opposite pattern to overpronation.

Why it matters

Because the foot rolls less, it absorbs less shock, so more impact can travel up the leg. Supinators often suit soft, cushioned shoes that add the shock absorption the foot is not providing on its own. Like pronation, it only matters if it causes discomfort.

How it is identified

Supination shows up as wear on the outer edge of the shoe, especially the outer heel and forefoot. A gait check confirms it by showing the foot staying tilted outward rather than rolling in. High, rigid arches are often associated with it.

What to look for

If you supinate, look for neutral shoes with generous cushioning and flexibility rather than stability features. Stability shoes can make the problem worse by pushing the foot further onto its outer edge.
