I just received these, so may need to revise my review over time. I ordered one size smaller since I wear these boots barefooted. One size down works perfectly for me in this case. (I wear an 8M, ordered a 7.) They feel snug enough, that when the fur inevitably compresses, the boot should still be snug enough. My heels slip a little, which is worrisome. Hopefully that won't get any worse, but it probably will. I blame the slight rear projecting angle on the back of the boot.  The quality seems good. I have no reason to believe these are rip offs (as some had suggested,) and they have the authenticity verification tag inside one boot. The lining feels like genuine sheepskin, and of course, they are quite comfortable. The opening of the boot is a little snug on my calf (my calf measures 13.5" where the boot tops out,) so hard to get a looser trouser to tuck inside. I usually wear them with legging type pants, so no problem for me there, and the slimmer opening is more flattering. The height of the boot is 11.5" (measuring the suede only along the inside seam.) All in all I am pleased, but I miss the older Kirkland sheepskin boots, which were the best for comfort, fit and durability, at a fraction of the price. These are the closest I've been able to find to the Kirkland boots. (Funny, most people are trying to find boots that approximate UGGs, and I'm trying to find boots that approximate Kirkland's brand.) I like the heftier sole as it looks like it will provide better traction and wear, and it doesn't add any significant weight. Will see how all works out after a little breaking in.
