The ROTOTO Double Face Crew Socks "Silk & Cotton" are meticulously knit in Koryocho, Nara Prefecture — the town leading Japan's finest sock production. Crafted by skilled artisans using a rare double-layer knitting machine found exclusively in the town, these socks showcase the depth of ROTOTO's technical and cultural heritage.

The construction pairs a colored cotton outer surface with an undyed silk lining, finely knit into a pile structure that fully enhances silk's natural properties. Silk delivers exceptional moisture absorption, heat retention, and temperature regulation, while the pile surface creates a soft, cushioned feel against the skin.

The result is a sock that feels refined and comfortable across all seasons — keeping feet warm in cooler months, cool and dry in warmer conditions, and pleasant to wear throughout the day regardless of temperature.

These socks are produced in northwestern Nara Prefecture, a region whose sock manufacturing tradition is deeply rooted in centuries of textile heritage. ROTOTO values the knowledge and craftsmanship of local factory artisans who preserve this tradition, believing that truly exceptional socks can only be made through the combination of the right material, the right machine, and the right craftsmanship.
