Life shouldn't be lived on the fringes of polarized extremes, and neither should your sock length. Yes, there is a world where performance, comfort, and durability exist between the confines of knee-length and ankle socks, and it's called our Mountain Mid Socks. They have a moderate four-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. 4" cuff height (size Small/ Medium)Lightweight underfoot cushion adds an extra buffer to trail vibration, which also combats friction and hotspots over the course of a ride.PowerBand mid-foot arch supports the foot and secures the shape and fit where the foot needs it most.Reinforced Y-heel and toe add to the long-term durability and comfort of the socks.VaporRize™ Merino blend yarns naturally control heat and moisture buildup, while also fighting against odor.
