I typically buy LaCrosse boots a size smaller than my sneaker and shoe size. The boots seem very warm so far, but I bought a box of "Hot Hands" to put in each boot in case of sub 20 degree weather. I take photos in the NJ Pine Barrens and stand motionless for up to an hour at times, and I really needed warm boots. I wear these boots with Carhartt Men's Arctic Wool Heavy Boot Socks. I could hike for miles in these, although they are obviously heaver than non insulated boots.
EDIT: It was 11 degrees on January 8th, and I waded through the Oswego river, photographing 8" of snow in the forest. My feet were very comfortable in these boots. Walking is easy, and they are warm, even in very cold weather.

I only wore them out a few times so far but they were great. On my longest trip the temp outside was about 30, and I went through a large beaver dam area. I was in mud and water and my feet felt perfect. Ive also worn them to shovel snow and my feet felt great. They are a little bigger then my other size 11's but that leaves plenty of room for a nice boot sock. I would probably need a 10 if I didn't want to wear a thick sock.

Bought these Alphaburly 800 grams with Amazon fulfillment. Ordered size 8D. The sticker in the boot shafts both said 8. But I took out the footbed and noticed right boot under insole had 8 stamped, the left had 9 stamped!!! Holding them side by side, the left was visibly longer. Don't just look at the labels! Luckily my left foot is half size longer. The left boot also had second footbed which made the initial fit noticeably tighter, when I took out extra footbed the fit was much better.

Normally wear size 10 D width in athletic shoes, have pair of Danner Quarries in size 10 D. Normal dress shoes usually 9 or 9.5 D width. I have a low volume foot (more people need tell their foot volume in addition to length and width when describing how a shoe fits in their reviews). I briefly tried on size 10 in local store, they were huge w/ thick wool socks, the store did not have 9 or 8 to try on. When I ordered I sized down to an 8, the right boot size 8 was just a touch too small, but the left boot size 9 fit my slightly longer left foot better in length, width and only slightly loose in volume. Returned the mismatched pair for hopefully another pair both in size 9.

Construction seemed good, but can't say long term. Assuming they hold up, and insulate well, I guess I would rate the boot at least 4. But giving 3 stars for mis-matched pair Amazon sent me.

Boots ran big and had to return. Outdoor Equipped has a no exchange policy which caused me to have to pay return shipping (over $20) and would have had to pay a 20% restocking fee had I not ordered another size smaller from them. In this day and age I find this to be a bad return/exchange policy considering Zappos doesn't charge either return shipping or restocking fee if the size isn't true. Happy with the smaller sized boots but Outdoor Equipped has terrible policies and for this reason I would not recommend buying anything from them. I would however recommend these boots for any hunter who wants to keep their socks dry.

I got these boots in anticipation of my upcoming annual winter fishing trip, where the nominal seacoast temperature is 30-deg.F with a constant 30MPH wind (so it feels colder). We go out all day in that weather. Over the years, I have been swapping out pieces of my kit as I learn what works in that setting and what does not. I used several other makes and models of boots, and they held up well for the first two hours or so. By the end of the first day, I was moving around a lot more, including doing leg squats, just to (try to) stay warm. Also by the end of the first day, the metal fittings on most of the clothing begin to rust. I have learned my lesson. I am a size 11.5, so I went with size 12 to accommodate for thick wool socks. I will be better prepared with these boots, no doubt. Their construction quality is great. My family members who are hunters and are familiar with LaCrosse (and specifically this model of boot) have had all good experiences with them. I will, too.
