Prior to finding these I was stuck between wearing ski socks or thick wool crew socks in the winter. The crew socks were too short, and the ski socks were a little too sporty in style. Now I've got the perfect dressy/casual sock to wear in winter. They're not overly thick, just enough to give a little extra warmth, the Donegal tweed pattern looks great, and the mid calf length is perfect. I went with the khaki twist and mid grey, and plan to order two more colors.
