I would like to introduce patented products that we often see without giving them a second thought.
This time, I will be introducing “Tireless Socks.”
Tireless Socks are socks that utilize patented technology from Nishigaki Socks Co., Ltd. (Yamatokada City, Nara Prefecture), which was also featured in the Japan Patent Office’s newsletter “Tokkyo” Vol. 65. Attracted by the colorful design, I decided to order a pair to try them out.
According to the website, these are “high-performance socks that reduce fatigue through a special taping knit, non-slip woven grips, and cushioned knitting on the sole.” While the product packaging only mentions cushion knitting as a patented technology, it appears that grip knitting is also a patented feature.
When I tried them on, the cushioning under the arch felt very firm. Essentially, it feels like the type of insole you’d place inside your shoe is attached to the sock itself. Also, even though there isn’t any obvious anti-slip material visible at first glance, they were surprisingly slip-resistant, making them easy to walk in and comfortable.
These days, you can buy a wide variety of functional socks at local home improvement stores and workwear specialty shops. Even something as simple as the way a sock is knitted has a lot of depth to it. I really feel the power of the inventions and ingenuity that drive the world forward, and it gives me a sense of reassurance.
Please note that the used trademark “Tsukare shirazu no Kutsushita (Tireless Socks)” is registered as “Tsukare shirazu no Kutsushita (Tireless Socks).”
