The Five Stripe KOM sock, (short for 'King of the Mountain') is designed to be a performance sock for all of you trail heads who have one speed... "lightning fast". It's our ideal sock for any kind of cycling, mountain or road because they have no cushion and are designed with a vapor wicking weave that cools your feet off as they heat up. If you prefer a thinner sock with that next to skin feel, these are your go-to's. Great for hiking, trail running, and anything that makes you sweat. Crew length with some decent stretch. If you're looking for something shorter try the 3 stripe version, or the KOM sock mid. Either way they are guaranteed for a million miles. Howl at the moon and get out there! These will post your next PR!!! Two sizes, (S-M : Womens 6-10, Men's 5-8  |  L-XL:  Women's 10-13, Men's 8-12) Unisex.
