Gregge 15 Sock
Your rides run the gauntlet from too warm to too cold, and you don't shy away from your bike because of a little drizzle. The Castelli Gregge 15 Sock is constructed of a merino wool blend that naturally regulates temperature and manages moisture—standing up to both perspiration and precipitation. The blend is soft and flexible, and it's constructed with a reinforced toe and heel for extra durability. A thicker footbed cushions your foot against the stiffness of your shoe and improves warmth retention to minimize chills.

Castelli socks are iconic in the cycling world. Made in Italy, these socks are a work of art. The quality is 10 out of 10.
I own several pairs of Gregge 15 and Castelli Quindici (15) wool socks. Love them both. The only difference I can tell is that the color schemes are different. Castelli officially rates them both for use in 60° F down to freezing weather (with shoe covers!).
Sizing: The sizing chart at the official Castelli website is correct.
Cycling shoe size: 36-39 = S/M
Cycling shoe size: 40-43 = L/XL
Cycling shoe size: 44-47 = 2XL
I wear a 45 in Shimano. The 2XL fit perfect -especially after a few washings (wool does shrink a little). If you wear a size 45+ cycling shoe, definitely buy the 2XL.
Nice sock for colder weather
- Familiarity: I've put it through the wringer
- Fit: True to size
I bought these socks when I was buying several pairs at the begining of the riding season. These are great, a little on the thicker side so I like them on cooler days. Stay up well and super comfortable.
