Protect your feet.
If you're fond of comfortable rides, you should care about your feet. Besides bonking, nothing makes a 10k climb worse than frozen feet or hot spots—yes, they can go together. Luckily for you, Castelli cares about your feet in the shoulder seasons, and made the Thermolite 13 Sock. By using patented fabrics, and an anatomic design, the Thermolite 13 will get you into, and out, of winter without a single frozen digit.
Castelli's Thermolite 13 Sock is made from the patented Thermolite fabric. Meant for the in-between days, Thermolite retains warmth through insulation instead of bulky design. To achieve this, Thermolite uses hollow-core polyester fibers that breathe, wick, and keep internal temperatures consistent. Coupled with a flat-knit construction, and a mid-foot support band, the Thermolite 13 provides a precise fit that's free from hot spots and chafing.
The Castelli Thermolite 13 Sock is available in sizes Small/medium, Large/x-large, and XX-Large. These socks are available in the colors Black and White.

- Familiarity: I've put it through the wringer
These are great winter socks, and I like them extra higher, keeps things a little warmer especially when your not wearing leg warmers cause it not to hot but not to cold
