These are stretch tabi socks made with Toray nylon tricot fabric. My husband wore them for a few hours during the wedding ceremony and reception. They have been washed since. His usual shoe size is 26.5 cm. They are easy to wear because they stretch. (My wife and I have also used the same product in a different size several times and like them.) In the second image, there appears to be a thread snag on the instep of the left foot, possibly from when they were purchased. We didn't notice it when we used them, and only realized it when listing them. It's basically unnoticeable, but please be aware of this before purchasing. Retail price: 1650 yen (including tax)
