RoToTo socks are produced in the NARA region of JAPAN; an area renowned for making its own specialised YAMATO GASURI cotton. The best cotton makes the best socks.
Driven by a guiding principle of manufacturing "lifelong consumables", RoToTo refuse to partake in the modern practise of automated programmed production. Instead, they employ experienced craftsman to make small batches of socks on specially selected knitting machines.
RoToTo also have an admirable commitment to reducing waste. The binding rings on the socks are repurposed waste from the production process.
