Abstract: An anti-slip sock includes a sock body configured to be worn on a human foot. The sock body woven from fabric yarn threads defines opposite outer and inner surfaces and has a sock sole. The sock sole corresponds to a sole of the foot with the inner surface facing the foot. The sock sole is woven from the fabric yarn threads together with anti-slip yarn threads. The sock sole is provided with a protective means that prevents the human foot from contacting the anti-slip yarn threads. Thereby, contact between the anti-slip yarn threads and human skin and in turn the risk of skin irritation can be eliminated.
