Quick Definition: A shank is a supportive strip (made of steel, fiberglass, or composite) tucked inside the midsole under the arch to provide torsional rigidity and arch support.
Structural Role of the Shank
The shank bridges the gap between the heel and the ball of the foot. It prevents the arch section of the shoe from collapsing upward when stepping on sharp rocks or climbing ladder rungs.
Key Benefits
- Protects arches when standing on narrow rungs or shovel blades.
- Maintains structural sole integrity over heavy wear.
