Stability shoes offer a good blend of cushioning, medial support (to limit excessive inward rolling of the foot, which can cause injury) and durability. To provide stability, they often have a medial post or dual-density midsole - these are features that provide a firmer density under the inner edge of your foot. They are usually built on a semicurved last.
You should buy these if: you’re a midweight runner who doesn’t have any severe motion control problems and wants a shoe with some medial support and good durability. Runners with normal arches are often fine in stability shoes.
