Thank you for viewing. I accidentally purchased this item and was unable to return it, so I am listing it for sale. It is listed as 21cm long and 8cm wide, but some reviews say that people with feet around 23.5cm have also used it. If you are into sports, I would be happy if you could use it. In my case, I would like to refrain from transactions where there is no communication, as I cannot see your face. The sock pattern is folded. Please understand. #SportsSocks #YogaSocks #NonSlipSocks #IndoorSportsSocks 【Important Notes】 ● Please be sure to read the profile before purchasing. ○ Even for new, unused items, and items only tried on, please refrain from purchasing if you are seeking perfection or are very sensitive, as they are stored and inspected by amateurs. ○ Items may be shipped in simple packaging.
