The skin on the heel of the foot can be up to 2 cm thick, specifically the subcutaneous connective tissue under the heel.
This substantial thickness serves a critical function: distributing the compressive forces exerted on the heel during walking, especially when the heel initially strikes the ground (stance phase). This cushioning effect protects the underlying structures and contributes to comfortable and efficient movement.
It's important to note that this measurement refers to the total thickness of the subcutaneous connective tissue layer under the heel, which includes the skin and underlying fat and connective tissue. The epidermis (outer skin layer) itself is considerably thinner, but still thicker on the heel than most other areas of the body.
