Precision-built and quietly powerful, the SIA Heir Low (Knight runner) is a modern performance sneaker designed for movement, control, and everyday versatility. Balancing technical detail with understated design, this silhouette delivers function without excess—and impact without noise.

The layered upper combines breathable mesh with textured leather and suede overlays, creating depth while maintaining durability and airflow. black gives the sneaker a refined, utilitarian edge that transitions seamlessly from active wear to elevated street styling.

Underfoot, a sculpted cushioned midsole absorbs impact and supports natural motion, paired with a rugged rubber outsole engineered for traction and control across varied surfaces.

Fit & Sizing: Runs true to size; if you wear a half size or have a wider foot, we recommend sizing up.
