Finding the Best Sock for Race Day

The Best Socks for Obstacle Races, Mud Runs, Rucks and more

Other than the shoes that go on your feet the second most important item you wear are your socks. They are the barrier between your feet and the elements. Choosing the right sock for race day can be an important choice. When it comes to the choices out there it's important to go by the first rule of OCR - NO COTTON! Picking the right sock on race day can make a huge difference in your comfort on course and after the race. 

The key attributes to look for when picking your socks for your next mud run, obstacle race, ruck, or other extreme endurance event are material, wicking ability, comfort, padding, and fit. A good OCR sock will wick away water, as well as help pad your feet from the tiny pebbles, mud and other debris that might slip into a shoe, as well it should fit your foot well and overall be comfortable. Below are some of the top choices in order of price to help make sure race day is as successful as possible because worrying about your feet is the last thing you want to do.
