The first use has no problem in particular. However, it is natural that no socks will smell when new. There is almost no deodorizing effect after the second time. I feel smelly than products that do not mention the deodorant effect. I am sorry to have expected it.
If I use 3 weeks in a week, I will have a hole in about a month, I would like to use something a little more durable and I would like you to introduce the best and strong durable socks that can prevent athlete's foot.
