Replenish your drawer.
After realizing you can't remember the last time you bought a pair of cycling socks, you also realized you're down to only one matching pair and a peloton worth of orphaned singles. Before this season's training picks up, replenish your collection with the Castelli Quattro 9 Sock. Simple and streamlined, the Quattro's classic design caters to minimalists. It comes with a highly breathable polypropylene construction prepared to keep you dry through sweltering summer weather, as well as a midfoot support band to prevent bunching or shifting fabric from causing blisters.

- Midfoot support band encourages a slip-free fit
- Hightly breathable polypropylene knit keeps your feet dry
- Reinforced cuff stays in-place without pinching

If you ride in Castelli kit you need to wear Castelli socks. And why not? They make great socks.
These feature more subtle styling than some Castelli socks. And 9 cm is the perfect height. 6 cm is too low -tho this is personal.
All the colors look great. Thin, light, and well ventilated. Made in Italy.
Sizing: The official sizing chart at the Castelli website is best:
Cycling shoe size: 36-39 = S/M
Cycling shoe size: 40-43 = L/XL
Cycling shoe size: 44-47 = 2XL
I wear a size 45.0 in Shimano road shoes. The XXL fit perfect,
