I don’t feel comfortable with stockings, so I use foot covers especially during the hot seasons. The foot cover I bought the other day said “patented” in Japan.
When I looked up the patents of Gunze Co., Ltd., the company that sold these foot covers on J-PlatPat, there were several patents related to foot covers. I didn’t know which patent was the foot cover I bought because the patent number wasn’t written on the product label, but I felt once again that the efforts of these companies support a comfortable daily life.
