The anti-slip structure includes a first circular inner portion, a second outer portion, and a third core portion. The third core portion comprises an assembly of three pin structures for providing traction over ice. Each pin structure has a wedge-shaped base portion secured within the first circular inner portion and a pin extending through the second outer portion to the tread surface. The three wedge-shaped base portions combine to form a circular base portion for the assembly.
