These are toasty warm around the foot. The build quality is great, with thoughtful touches like a heel pull that works well with winter gloves (field verified).
The reinforced heel and front help mitigate moisture migration into the down from wet snow. These shoes have some grip, but stay on flat terrain. Hard packed snow is not your friend while wearing these.
I wore these on a winter backpacking trip, with mid-weight merino socks, in single digit temperatures. My feet were toasty warm — mostly (more on that in a moment). They are very lightweight and pack down to about 3/4" in height each (in size XXL). Soft fleece cuff is nice but not really noticeable unless I'm not wearing socks (only once in trial at home).
My 1.5 Star reduction? Well...
The XL size in men's, the largest SD makes, is spec'd as a 11.5-13 bootie. Not a chance. I am a true 13 and these press on my big and 2nd toe. This was really highlighted in those cold temps I experienced while camping. My feet were toasty except for the ends of my two biggest toes on each foot. I suspect that is because the moccs are under-sized, and my bigger feet compress the down into nothing on those toes.
My feet were also tender from the hike, and that didn't help the way my toes felt. I will say that only the tips of said toes were "moderately cool", but not uncomfortable. The discomfort came from the inaccurate sizing leaving my toes a little squooshed. If you are more than a 12.5, don't buy these (12.5 try on first).
I only paid $19 and they don't make these larger so I kept them. I'm trying to stretch out the length if I can.
