The Castelli Invisibile Cycling Sock is for anyone who prefers socks not to play a big part in their cycling outfit. Under a shoe it's pretty much exactly as the name would imply (and you don't need to be fluent in Italian to figure that one out!)

If you're one of those who prefers a shorter sock that simply works as a technically excellent layer between foot and shoe, then Castelli's Invisibile sock may be the one for you.

You'll still benefit from Castelli's striking design when you take off your shoes, and you'll enjoy the exceptional technical specifications for which Castelli are famous right to the end of your ride. But sometimes subtlety is everything.

Who's Behind It?

Q. What do a 19th century Italian tailor, a designer for the Milan Ballet and the first ever lycra cycling shorts have in common?

A. They are all part of a rich 140 year history that's led to today's most recognised brand in cycling: Castelli.

Throw in a heart attack on a famous Italian climb, family feuds, Olympic gold medals and controversy in the pro peloton and it begins to sound more like a Sicilian soap opera than the backdrop to a cycling brand. But then again Castelli is no ordinary brand.

Today, Castelli's scorpion emblem is arguably the single most recognised in cycling. Iconic is an overused word these days, but the Castelli brand surely qualifies.

We first discovered Castelli on our year long ride through the Americas in 2010, when our founder Liz (pictured) wore Castelli shorts and loved them, so stocking them seemed an obvious choice. But we're almost as captivated by the story behind the name as the kit itself!
