A great pair of socks makes a big difference in foot comfort. And the Castelli Rosso Corsa 9 Sock is a great sock.
So we’ve made the main foot part of the sock in our Air Mesh to enhance breathability and given it a central foot band for support. The ankle cuff is 9cm high for a bit more length and features a top band that is doubled over so that the elastic will stay perfect over time. The Meryl Skinlife fibers contain naturally bacteria-static silver ions so that bacteria will not grow in your shoes, yet it doesn’t harm your feet.
