RoToTo’s socks are produced in specialist factories in Nara Prefecture and Goryocho which both have more than 100 years history in sock manufacturing. They use many different types of sock knitting machines depending on the sock they’ve designed, from old-fashioned machines that are impossible to computerise to state-of-the-art technologies. These double face socks have been in ROTOTO’s collection since the establishment of the brand. Designed with an inspiration from mountaineering socks, the item features merino wool on the surface and undyed low-count organic cotton fabric as the lining to create a soft and thick feel like a sweatshirt. The liner material feels fluffy and comfortable with a napped surface.
