by the way, i have had those boots for five years and hunted har in them and they have held up extremely well.

I have discovered over the years that the higher the boot, the warmer they keep your feet. I have a pair of 15" Rocky lace-up snake boots that are the warmest boots I have ever worn, yet not so warm as to induce sweating.

Christian Emter is right about sitting too long in one place, but it seems that a lot of heat is lost through the top of the boot in the shorter type boots.

I have a pair of 1000 gram rockies. In real cold weather they are great. I wear a pair of thin wicking socks under my wool ones. Keeps my feet from sweating while climbing the mountains to my stand sites. Helps keep them warm while sitting. Another thing to get is a pair of slip on boot covers for when you are sitting on the stand. Theyre like little insulated blanket bags for yor feet with boots on. I have never tried them but know people who swear by them. Just dont try to walk in them youll end up on your back!

I forgot to add. Do they still sell "battery socks" ?
That would help you too !

BOGS makes a 15" camo boot called the "High Classic", or a 17" called "The Blazer". They don't use a gram rating system, but rather rate their boots for temp. These boots are rated from 60 degrees to -30 degrees, and have MT (moisture technology)to eliminate sweating issues. I haven't tried them myself(due to a temporary lull in funding) but have heard nothing but great reviews on them.

There is another post asking the same thing from yesterday. Here is my response and I hope it helps:

ahhhh, one that I can give great advice!!!! First of all I am going to guess that you are using insulated boots. Go uninsulated (don't worry it will make sense in the end). Wear a good pair of MERINO wool socks. I get mine from Bass Pro and buy RedHead. They work great. Also, invest in Arctic Shield boot covers. Wear one pair of socks to the stand. Once you get there, change your socks and put on the boot covers. Climb up, and stay warm all day. Also, make sure your boots are not tight. I buy boots too big so I have lots of toe wiggle room. This also helps so you can wiggle your toes and get the blood moving to warm them up. Also use foot powder. This is important in keeping them dry from sweat. Put the powder in your sock, not the boot because then when your feet sweat and the sock is wet, it starts to get gummy and cakes up. Almost forgot, loosen your boots a little when you put the covers on. Allows air to move around in the boot.

I wear uninsulated leather boots with thick socks for stalking/still hunting, and insulated boots while sitting in a stand. I often get cold feet due to insufficient insulation, but I've put hand warmers in my shoes to remedy this on cold days.

If you have the money to get some shoes specifically for the really cold weather, I think you'll be pleased.

rocky boots, 1400 grains. they work great for me, and i have the same problem as you.

i just got a pair of cabelas Whitetail Extreme boots. I got them with 1200 gram thinsulate. They seem to be pretty good so far. They are scentlok and gortex. They werent very cheap though.i usually have my toes freeze too but these work great so far.
