Because it wears for a long time, it purchases with a smell countermeasure. It is a firm build. It seems durable. I feel that the smell is suppressed. Whether it is important after the number of times of use increases.
The feeling I used is nice. However, as it is explained in the explanation, it is strong, because it is two sheets ... It is not such a feeling. I thought that it was for work but I will try other socks as well.
