You have your ankle socks and then your knee-high socks, but like the old story goes, sometimes you want something that's just right. Yes, there is a world where performance, comfort, and durability exist between the two extremes, and it's called our Women's Mountain Mid Socks. They have a moderate three-inch cuff height, and feature a lightweight blend of our VaporRize and Merino yarns. These yarns work in tandem to naturally control temperatures, manage sweat buildup, and fight odor. In other words, they're comfortable. And to further ensure this, we've included a mid-foot arch support and a light underfoot cushion to help absorb vibration and chatter from the trail.
