I have bought various short socks (Nike, Adidas, etc). These are by far the best ones I have tried. The fabric is incredibly durable over time. It is neither thick nor thin, which helps it maintain its shape, does not fade, does not unravel, and does not develop holes. They have a great fit and do not squeeze the foot or especially the toes, but they also do not sag. Unbelievable. They are also as tall as needed to protect the heel from ankle boots. I even wear them in the summer without making my feet hot. I hope Company A does not change the materials and that they remain just as good. I should mention here that I use them for everyday wear and not for sports.
