These cotton-wool socks are warm and soft to the touch. Blending cotton and wool in a 6:4 ratio, the socks combine the excellent heat retention and moisture wicking properties of wool yarn with the durability of cotton yarn. The surface is uneven to create a unique texture, and a special dyeing technique is used to create a denim-like color with depth.

D&DEPARTMENT's original socks are made in Nara Prefecture, one of Japan's major sock manufacturing regions. Thread from cotton-wool socks is spun by KAYAZAWA Shoten in Nara prefecture, whereas the sock manufacturing is done by Souki Inc., which is also located in Nara.
KAYAZAWA Shoten is a thread distributor founded in 1948 in Nara. We got to know them through the publication of "d design travel NARA". And then, in 2018, we decided to create original socks with them, because we empathized with their "efforts to promote sustainable manufacturing".

Seiichi Kayazawa, the president of KAYAZAWA Shoten, doesn't sell just any thread. He only sells thread that he is sure sock manufacturers would want. While growing up and watching his business, his son Ariatsu and his wife Ryoko founded "saredo", a sock brand that embodies the best of Nara's sock-manufacturing technology and skills.
"These may only be socks, yet have an importance nevertheless."The Kayazawa couple's explanation of the "saredo" brand name is as follows.
"S"ustainable - We can go on forever, maintaining the present state without destroying the global environment.
"A"lternative - Another choice, heterogeneous, not in type.
"RE"novation - Innovation, repair. We create new value, reproduce and reconstruct.
"DO"mestic - Based on the domestic inspiration of the country = the do-it-yourself spirit.
Mr. and Mrs. Kayazawa work on manufacturing with 4 keywords "Faith", "Honesty", "Humility" and "Delicate", based on the spirituality and artisan disposition of the Japanese people. Moreover, they propose and market thread that gives the "nevertheless" impression, rather than "only be..." one.
They recycle materials that would normally be discarded without creating waste, rather than simply creating a product cycle. They also like to meet people from every corner of Japan and emphasize activities to expand the sphere of production. Using the 4 words as keywords, they propose "a sustainable lifestyle spun from waste cotton". They feel that everything about Nara's craftsmanship is embodied in these words: "These may only be socks, yet have an importance nevertheless."
