A great over-the-calf heavy weight sock from Smartwool. The x-patterned 4 Degree™ Elite Fit design hugs your foot and helps prevent blisters and hot spots by holding the sock in place and keeping it from shifting and bunching. This is the warmest sock in the PhD series from Smartwool. This model is not as warm as Smartwool's mountaineering socks, but has a snugger, and tighter fit and feel.
