The invention relates to a covering (1) for an extremity of the human body, in particular a foot covering, comprising a casing (2), which is made of an extensible material and encompasses the corresponding body part in a contacting manner. Nub-like protrusions (4) for stimulating reflex zones are attached to the inner surface (3) of the casing (2). The casing (2) is made of a rubber-like elastic material, in which the nub-like protrusions (4) are formed. With the covering pulled over the body part, the nub-like protrusions (4) cover the reflex zones. The nub-like protrusions (4) have different sizes in different reflex zones. Optimal stimulation of the reflex zones is thus achieved.
