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 organic cotton no-show socks are developed to be worn with sneakers. The 3-D heel design and elastic yarn used around the heels make the item stay-put. The length is short enough to hide away in sneakers. There are seven colour options available for this item from basic to pale ones, so you can choose the colour depending on your mood.
