CoolMesh II Crew Running Socks for Men and Women – Eco-Friendly

The double-layer construction is not a marketing story: the inner and outer layers slide against each other, so shear that would otherwise happen between skin and sock happens between two pieces of fabric instead. For hikers who blister no matter what liner-and-sock combination they try, this often works when nothing else has, and the Coolmesh knit vents better than most double-layer socks. Two layers also means twice the fabric. These run warmer and dry slower than a single-layer sock, which is the wrong direction on a hot August day or a trail with repeated fords. Cushioning is minimal, so under a heavy pack on rocky trail your feet feel the ground. They cost about what merino socks do but they are synthetic, so they will smell after two days. And if you size them wrong the layers bunch, which causes the exact hot spot you bought them to prevent.
