Over too many years to remember I have tried socks from all the big names, Assos, Defeet, Castelli etc.etc. RST have come up with a very well made sock with excellent colour and shape retention after numerous hours on the feet and in the subsequent wash.
Very pleased to report they have surpassed expectations. Thoroughly recommended.

Can't really say a lot about socks can you but these are a bargain. Other shops would be asking £10 to £15 for quality like this.
