Abstract: FIELD: manufacture of soles with pins for shoes. 
     SUBSTANCE: flexible sole has lower working surface consisting of less flexible outer layer, upper surface, more flexible inner layer positioned therebetween, and inwardly retractable pins fixed within inner more flexible layer. Each pin has anchor part embedded into more flexible layer, tip protruding beyond plane of lower working surface, and core which connects anchor part with tip. Flexible material is non-uniform in flexibility extent and has lower flexibility in zone adjoining outer part, near sole surface, and higher flexibility in zone adjoining inner part of sole. Anchor part of pin is embedded into sole in its more flexible part so that body of more flexible material is provided between sole and upper surface. On wearing of shoes and applying of compressive deformation force to sole lower surface, tip is retracted into sole under the action of force applied by anchor part of pin to more flexible inner part. Less flexible outer part of sole provides wear resistance on contacting of lower working surface of sole with rigid surfaces during wearing of shoes. According to another version of sole, lower surface of sole has annular slots running around pin tips to enable bending of tips upon application of pressure to sole lower surface during walking, for example, over rigid surface. 
     EFFECT: improved adaptation of flexible sole equipped with pins to variable pavement or ground surface and to user's weight so that pins readily cooperate with said surfaces into which these pins are designed to penetrate.
