These chunky socks are crafted using a rare traditional machine, employing thick recycled cotton yarn typically favored for hand-knitting. ROTOTO consistently chooses recycled cotton yarn sourced from a yarn company located in Nara Prefecture. Their environmentally conscious approach involves utilizing cotton waste from Japanese spinneries, re-spinning it using innovative techniques. While the material may be prone to fraying, the mixed heather color achieved with two-strand yarn helps conceal dirt and fuzz, ensuring a more enduring appearance.

The sock production in the northwestern part of Nara Prefecture is thus originated from the area’s centuries-long tradition of the weaving industry. And that is why Rototo places more value on manufacturing that requires a lot of discussion with factory craftsmen who preserve the tradition and history. Rototo’s socks can be made only with a combination of the right material, the right machine and craftsmanship. They aim to preserve the tradition inherited from their ancestors.
