The Base Command Crew sock creates a mid-weight cushioned barrier between your foot and your boot with the added benefit of total climate control. FreshTek™ is our special treatment that wicks moisture while eliminating odour-causing bacteria to keep you feeling fresh and dry throughout the entire run. These crews are reinforced in the heel and toe with Infiknit™ for guaranteed durability and designed with a merino wool blend and performance arch support, allowing you to stay comfortable while out in the elements.
