Abstract
An improved anti-slip spike structure is provided, which is used in soles of snow shoes or special anti-slip shoes. In this structure, an anti-slip spike is mainly arranged on a sole surface. An external side of a metal spike body is wrapped with a hard rubber body into a solid cylindrical rod-shaped rubber spike. Then, the solid cylindrical rod-shaped rubber spike is placed into a shaping module to be integrally formed with a rubber sole. Since the rubber spike is entirely wrapped and has a large placement plane, it is easy to position the rubber spike in a mold. In addition, when the rubber spike is pressed to be shaped, the spike does not skew or shift and is homogeneously shaped with the rubber, so that the spike is completely joined to the sole. In this way, the sole is provided with comfort and flexibility, as well as firm joining against trampling and significant anti-slip safety and practicability.
