RE: warm boot referral?
Go to your local Army & Navy Surplus and pick up some Mickey Mouse boots.They are army issue cold weather gear.
You can get them online from Sportsmans guide.Somebody told they aren't the originals, but I know people that have them and they work for them.
Don't let the rating on the boots fool you.The black are rated at -20 and whites are rated at -70.These things keep your feet toasty.Check out what alot of people in Alaska and ice fisherman wear.You'll find it's these boots.
