A non-slip self-supporting orthopedic device includes: an upper disk slidably engaged with the rod and externally provided with a hinge； a lower disk, connected with the orthopedic device allowing the elastomeric foot to project downward, and externally provided with a hinge； and arms with upper element, lower element and spring adapted to hold the arm in folded configuration. The movable mechanism can take an enlarged configuration, in which the upper disk contacts the lower disk and the arms are folded. In an elongated configuration, the arms are in axial configuration following the pressing of a button connected to a kinematic mechanism causing the arms to take the axial configuration. The reversible connection system allows the reversible disconnection of the lower elements of the arms preselected by the hinge, determining the lifting of the entire arm in a vertical position by rotation around the hinge.
