Quick Definition: A medial post is a firm section of high-density foam or TPU plastic built into the inner side of the midsole to counter inward arch collapse.
How Medial Posts Support Your Foot
When an overpronating foot strikes the ground, weight shifts inward. A medial post creates resistance beneath the arch, preventing the shoe midsole from compressing prematurely on the inside edge.
Key Benefits
- Prevents excessive inward arch rotation during heel-to-toe roll.
- Extends midsole structural durability along high-wear inner boundaries.
