The Castelli Meta 9 Socks is a comfy summer sock that keeps you cool, even as a fairly tall leg tube.
The 9 is for nine centimeters, the cuff height. The sock is knitted out of CoolMax yarn, with a number of different knits to optimize moisture transpiration and comfort. Much of the foot has a waffle-knit, with a ribbed band around the arch to keep the sock in place inside the shoe. The toe and heel have a more solid knit for durability. The upper has mesh, waffle, and ribs all going at once. The ribs are at the top and back, to help provide gentle compression to keep the sock in place, while the mesh and waffle are there to make sure the sock breathes almost as well as bare skin.
The Castelli Meta 9 Socks are fashionable and summery.
