By repeatedly pre-washing the wool, we have developed a line of wool socks that are almost completely shrink-proof. Shrink-proof wool was selected to produce these Jacquard socks. This plush material has volume similar to a pile - enveloping the feet in softness and warmth. Suitable for autumn and winter.
