Some marketing stuff about the socks:
Anatomic cycle-specific fit
Stretch arch support
Durable heel and toe sections
Fully-fashioned seam free
Coolmax fabric provides excellent wicking and fast drying performance
But to me, they are good looking socks which come in a variety of different colours to match your kit/bike and are cheap.
Altura coolmax for comparison are at least £10 for 3 pairs.
