I also ALWAYS take a set of Icebreaker Merino wool 200 tops and bottoms with me to the mountains anytime of year. They can litteraly be life savers. You can wear them for a week straight and they will not collect body oder. They make great PJ's on a cold night if your sleeping bag isn't quite keeping you warm - they will keep you toasty. I have worn just the tops and bottoms with a shell while back country skiing in subzero weather, and as long as I kept moving, I was comfortably warm. Just last weekend, I was fishing in the Yellowstomne backcountry with just sandals, shorts and T-shirt when a T-storm rolled in dropping the temps from 70 to 40 in about 5 min with blowing rain, sleet and hail. I put the merino wool top on under my T-shirt and then put my ultralight rain shell overtop. I was very comfortable until the storm passed about an hour later.
To me, having 8 yrs of living, working outside mostly, hiking, and hunting, experience in Colorado the best sox are a Merino Wool Blend. Brand and mix can vary. The price can be 9.00 a pair for Browning or 4for20.00 from Sportsman's Guide. They are warmest, wear longest, and dont make feet sweat as much. When I worked in AK they used to say for winter "ABC", anything but cotton, and I really believe that. 100% wool sox are poorest choice as they dont wear long at all. Good luck on your quest for warm dry feet.

Re: "Good Wool Socks"
+1 on what montana rifleman says. i dont particularly like 100% wool socks as the thread in the weave tends to hurt my tender feet after a while. good lightweight wool blend longjohns are great also. the most extreme kind of hunting i have ever done out here is lion hunting. you are always in snow from akle to waist deep, usually in temps hovering around the zero mark and some hunts turned into marathons similar to the kudu persitence hunt on another thread here. wool is the only way to go.
on the other hand, dont forget to bring shorts and sandals on your october colo hunt. sometimes we have what is called indian summer weather at that time of the year and it is so warm you will not want wool....AJ
I really like the Cabelas brand wool blend, and others I know like them as well. I think what makes them stand out is the shape and elastic. Filson makes a great pair of warm weather wool socks which are very thin and breathable on parts of your feet and thick on others.
