Purchased online this summer. Worn three times in gray, once in black. I think they were about 2000 yen a pair. Socks for bunion relief Binchotan fiber, deodorizing, and excellent breathability. Manufacturer: HAYASHIKNIT Product Name: Binchotan Bunion Relief Socks Materials: Cotton, Rayon, Nylon, Polyester, Polyurethane Size: M (22-23cm) ○ Shaped like tabi (split-toe) socks, separating the big toe and the other four toes. Soft pile cushioning between the big toe and the index finger reduces pain and prevents deformation. ○ Pile cushioning is also woven into the base of the big toe and index finger, a structure that alleviates friction and impact when walking. ○ Power knitting using rubber thread is applied at a position that crosses under the five toes. This helps to naturally spread the toes. ○ Power knitting from the base of the big toe through the sole and to the top of the foot provides a taping function to correct the deformation of the big toe.
