I have my child who does Kendo wear them, and he likes them. I was happy to find these because there weren't many cute ones. I bought them for my 6-year-old son and 8-year-old daughter. They stretch well and feel good. However, they said they are thinner than the ones they used before. The socks are well-made, and they are happy to wear them! I thought the characters were cuter than they looked in the picture. My child loves the surreal pictures. My 9-year-old has a shoe size of 22cm, and the size was perfect. They arrived today. Because my feet are small, I bought these, although they are for children, because I couldn't find a suitable size. The size is perfect, but I thought they were a little too cute. I bought them because I was concerned about my 2nd-grade daughter's foot odor. When she came home from school after wearing them for a day, I was surprised because there was no smell at all! She also really likes them, so I want to buy them again. By the way, her foot size is 18cm, and I bought the smaller size (14-18cm). Sometimes her little toe comes out, but it was good to buy a smaller size. Among the few five-finger socks for children, the design is also cute, so I use them regularly.
