David Millar says:

"There's a story behind these socks. They are the best socks I have ever owned. I had numerous pairs back in the day, one of those random promotional gifts from a sponsor. Contrary to most random promotional gifts these puppies became my best friend. I saved freshly wrapped pairs and every time I had to open a new packet I did it grudgingly, knowing my collection was shrinking. I tried to get more off the sponsor, but they had changed supplier. I was heartbroken.

When it came to the subject of Chpt./// socks I told Steve Smith of Castelli, "I have the best socks in the world, but I don't know where they are from." So the search began. Steve and I gave our email correspondence the subject title: TBSITW (The Best Socks In The World). I couriered one of my last pairs to Italy to be studied by Laura in R&D at Castelli. Laura ultimately tracked them down to a factory in Northern Italy but the factory was no longer in business. So we had to start over and re-engineer the best sock in the world.

1.93 is the fruit of the quest for TBSITW. The footbed is made with ceramic thread. I don't know what this does, makes them awesome I think. The height is quite high; this is how I like them. They will lose a little bit of this height after their first wash, but minimal. The pattern is a code, or key, to the data we used to create the pattern on the base layer.

Each colour and line refers to an element - time, km/h, watts, distance, cadence, BPM. The best thing about them is you can wear them off the bike. I wanted socks I could wear with a suit if I wanted; these I can."
