The Klim sock performs perfectly in a wide range of circumstances. In warmer conditions the Klim sock wicks moisture and dries quickly. Wool content insulates and keeps you comfortable in colder conditions.
I've been wearing cheap moto socks for years, but decided to give the Klims a try on my last trip to Mexico. They are very comfortable, and even after 3 days of off road riding in Baja, they didn't get too funky. I'll be purchasing more.
