To start with the boots that I wear are oversized, to allow for thick socks and room for your feet to breath. They are "Kamik" rubber boots with a thick felt liner. They also have a drawstring to seal out the elements.($40) Available online at http://www.sportsmansguide.com They also have gortex boot liners, that work well for wicking away moisture and keeping your feet dry.($12) I get my heavy weight longjohns from there also (polypropylene $20 per piece) but well worth it, polypro balaclava $10, in extreme cold I double them.
H.S.sents makes a product called scent-a-way powder, that is for tough persperation areas and is odor free.
The socks I wear are from Walmart and are merino wool/polypropylene blend.
I use the hand-warm-ups and foot-warm-ups from Walmart(and there is a differance) The hand warmups have a tendancy to get hard when they absorb the foot moisture, whereas the foot warmups stay soft. There are socks designed to hold these warmers or you can take a small safetypin and fasten them to the top of your toe area.

The best of luck in all your hunting endeavors!!!

God Bless,
