I never paid that much attention to socks, and have many brands, Defeet,
Altura, Cannondale, Castelli, Rapha, Pongo, and many others.
Due to wanting specific colours, back in the day when
Wiggle/
CRC were still a reputable company, I ordered some Gripgrab SL long socks, and they truly feel luxurious, and are a notable step up for me, over every other pair I have tried.
One note of caution, they do size up larger that you might think, so even though I am a UK10, the medium is exactly the right size for me.
Back in the day I used to be able to get these for £10 a pair, not so easy now, but I already have my sock stock of yellow and black pairs :-)
