Boots were comfortable but my feet got very cold after about 30 minutes in below 0 temperature even with double layer wool socks.

Definitely kept my feet noticeably warmer, but my toes were still a bit cold...then again this was standing still waiting for a bus for 20+ minutes in single digit temps, so there may not be much that can help that. They are very soft, and do shed a bit. They are also so thick I couldn't fit my foot into my boot with my usual sock layers, so I had to lose some to make some room. Even with the shearing insole it was a tight fit, but luckily after a few wears everything settled out.

So far these boots fit good when i first got them they were a bit snug, but after a few uses they fit fine kinda broke them in I guess.  They kept my feet warm in snowy weather.

Were great boots, they were warm in the snow and are very comfortable and easy to get on. But they are hard to get off and after only 6 months of occasional light farm use the sole are coming off. They are still water proof but for the price...Really? Wouldn't recommend . Going to try bogs

These boots are both very comfortable and warm, but only after breaking in. The boots weren't initially all that comfortable, but after a break-in period (which for me took about a week) they are now VERY comfortable. I usually wear a 10/10.5 shoe and an 11 boot, and these are just a little big.

Is not made for extremely cold weather. I wore these in 23 degree weather and my feet almost froze.

They're for the most part warm. I had to spray them with ugg water repellent to make them water resistant. They fit good in the beginning but they lose there fit quickly. I'm looking to replace these boots. There return policy needs to work better for the customer.

I liked these boots a lot by the look so i bought them over the computer.  I returned them because once I tried them on, they were so confortable.  There is no cushion inside and i have a feeling it will be a very cold boot during the winter..

These were one of my splurges and I think they are very comfortable, cuter than your typical mud boot and very dry! My feet seem to be cold in the snow? So I will probably have a different pair of boots for snow and wet weather.  I just got them and have only worn them a few times so not sure if I would purchase again at this point, my feet are always cold so that is an issue for me~

Very warm, first time my feet are not cold walking around in 15 degrees, even with normal socks. I read reviews and ordered a half a size up, planning for thicker socks. EDIT after 3 months of 3-4 times a week wear, both boots leak.

In the winter, I tried these and found them to be very comfortable. Now that summer has arrived I find that my feet sweat a lot in them after a short time which results in a stinky feet and socks.

After drooling over these boots for a season or two, I broke down and bought them in January 2009.  I'm usually size 7.5-8 and purchased a 7.5; I should have gotten an 8.  They fit uncomfortably snug the first few wears but eventually I could don them without pain.  I wore them to Sundance Film Festival and throughout Chicago's harsh winter and found them to keep my feet warm 70% of the time.  I would lose feeling in my toes and could feel the coldness of the pavement or snow creep up through the sole when outside for a period of time.  In October 2009, the back laces to one boot broke and I had to buy a new set.  Not a big deal; just surprising and inconvenient.  The next month, the zipper to one boot broke.  I took it to a a repair shop who refused to fix it because, "Honestly, it's not worth the money.  It will cost at least $50 to fix.  Just buy a new pair of boots."  Before I tossed the boots, I took out the insole and noted that they were pretty much flattened after about 6 months of wear (it stays cold in Chicago late and comes early!).  I enjoyed these boots but alas, they didn't last.  I will not buy them again.

My feet get very cold in winter despite wearing Merrell fur lined clogs.  I put these in a pair of boots and they were too tight with thicker socks.  Barely ok with thin socks.  I would suggest getting your boots either in a wide width or a half a size larger to accommodate for this.  I ended up wearing these without socks and my feet finally got warm.  I did order about 6 pair of a thinner brand to replace all my insoles in my Merrell clogs.  I am still waiting for them to arrive.  I suspect they are coming from China, as its is taking 2-3 weeks.

These definitely kept my feet warm while snowmobiling... at first.

These are very warm socks, the only problem I have had with them is they were causing my feet to sweat. This might not be a problem for everyone but my feet sweat rather easily and they just didn't ventilate quite enough for me.

I would have rated this boot a 5 star had I not experienced the following. Had these boots sitting in my garage all day, then in the afternoon I put them on to go hunting. They were cool, sitting out in the garage, when I put them on. They never got any warmer, in fact my feet became very cold as the evening time came. The temperature was around 32 degrees and I think my feet weren't far from that. Everything I read about the boot reviews were mostly favorable, but I can't rate them any higher at this time. I will try keeping them inside the house and putting them on and see how that does and reevaluate it if needed.

Wore boots to use in snow, after an hour my feet were wet. I could not wear boots more than an hour, too uncomfortable.
