The inner sole of a shoe is made of an elastic to stiff material and has a generally smooth surface (20) adapted to the sole of the foot. At least one trough-shaped local depression (22) that forms a recess in relation to the (undisturbed) surface (20) has smooth round edges (24) at the surface (20). Within these edges, it has a base (26) that lies a few millimiters below the undisturbed surface (20). Its area is considerably smaller than the total area of the surface (20). A knob (28) projects in the central area of the base (26), and its free cap (30) lies essentially on the same level as the (undisturbed) surface (20). |
