Massage bead, a pair of shoes and cushion

A massage bead, comprising a massage body, below which at least two sets of extension twisting spring assemblies (ETSAs) are arranged, wherein the massage body is mounted on an external supporting member through the ETSAs;

• each set of the ETSAs comprises a twisting spring and an extension spring;
• each ETSA is located below the massage body and mounted on the external supporting member through the twisting spring, an upper extension twisting arm of the extension spring is connected with the massage body, and a lower extension twisting arm of the extension spring is connected with an upper end of the twisting spring;
• the upper extension twisting arm, the extension spring and the lower extension twisting arm connected with each other are arranged axially and in a tilted manner and in a clockwise direction or in a counterclockwise direction simultaneously relative to the massage body;
• and
• when the massage body is under pressure, each ETSA is compressed and twisted to generate a rotational pushing force together for pushing the massage body to rotate in the clockwise direction or in the counterclockwise direction, and deformation energy is stored when each ETSA is compressed and twisted so that the massage body resets automatically when energy is released.
