Since today was commute #4 of a 5-day work week, I've run out of wool cycling socks. They're all in the laundry and we haven't done a load yet this week of bike stuff.
So, I pulled out an old pair of thick, wool ski socks that I no longer wear, because they're too thick for my ski boots. Boy, did they work great! And, I was toasty warm all the way up to my knees!
I think those old socks just found a new life.
