I can now call already several pairs of these socks my own and could not fault it except for the price. The material is very breathable and comfortable to wear. Coming friend into the shoes a sweat, so you notice immediately after you have taken off his shoes, like degrades the moisture faster than with conventional cotton material I think. Tightening makes after some time no more problems because the socks adjust the feet and toes in the form and you develop your own technique reinzuschlüpfen quickly. I wear the socks now almost every day, not only for sports. On the recommendation of a friend I wear these socks also prevent athlete's foot, and they can also help to combat because the toes are separated to be athletes foot and blisters. The material looks after numerous washes good too, perhaps because we are not using a dryer. My conclusion is very positive, except for the price, therefore only four stars. I would also buy a more cost-effective 3 or 5-pack, there should be such a one.
