About this part
The MSR Thin MX sock, a mid-weight riding sock cut tall over the calf so it runs the full height of a boot with nothing bunching at the top. Thin is relative here: it is mid-weight cushioning, not a dress sock.
The fabric wicks moisture to keep feet dry, with integrated arch and ankle support and a form-fitting stretch that holds the sock in place rather than letting it work down inside the boot. Composition is 70 percent polyester, 25 percent cotton, 3 percent elastane and 2 percent spandex. Two colorways are listed across four part numbers, checkered and red with black.
