When youre on the trail you have enough to worry about without stressing on your sock situation. Thats why we created our durable no-fuss Mountain Tall Socks. They feature a lightweight blend of our Vapor Rize & Merino yarns which work in tandem to naturally control temperatures manage sweat buildup & fight odor. In other words theyre comfortable & to further ensure this weve included mid-foot arch support & a light underfoot cushion to help absorb vibration & chatter from the trail. Vapor Rize Merino blend yarns naturally control heat & moisture buildup while also fighting against odor. Lightweight underfoot cushion adds an extra buffer to trail vibration which also combats friction & hotspots over the course of a ride. Power Band mid-foot arch supports the foot & secures the shape & fit where the foot needs it most. Reinforced Y-heel & toe add to the long-term durability & comfort of the socks.4" cuff height (size Small/ Medium)
