Fox River's Gibraltar Extra-Heavyweight Merino Wool boot sock is a perfect (and never scratchy) sock for anyone seeking a dependable and exceptionally warm sock. The High Merino Wool content of the Gibraltar means good value and a perpetually dry foot (one of the most important qualities in any good athletic sock).

The Gibraltar's full extra-heavy thermaline cushion will keep you warmer, and added arch support helps with extended comfort. The Gibraltar's low-profile toe seam won't irritate tootsies. Like all Fox River products, the 7014 Gibraltar's Extra-Heavyweight boot sock is proudly made at their mill in Osage, Iowa.
