Our socks have been made in Japan for over 30 years. Last year I was told that my favorite "double knit" machines and the technician who kept them up and running retired. No more socks! Just recently, another factory in Japan contacted me to say they missed making our special socks and they did have a few of the double knit machines still working well. Double knit means more design variety but also greater strength and comfort on the foot. Very few of these machines exist in the world. Double knitting uses two cylinders which means longer production time and requires skilled engineers.
