Last of all, we’ll look at the skin of the foot. On the dorsum of the foot, the skin in thin and mobile. On the plantar aspect the skin is markedly thickened, especially in the weight bearing areas. There’s a generous padding of fat on the sole of the foot, especially on the heel.
The skin on the sole of the foot is tethered to the deeper tissues by numerous firm strands of fibrous tissue. These strands arise from the underlying bone, and the plantar aponeurosis, and pass through the fat, into the subdermis, keeping the weight bearing skin firmly in place.
