For $50 I expected way more than these slippers delivered.  They arrived and when I first slipped them on, I thought, THIS is what everybody was raving about??  The slippers felt very awkward initially, and the back would slip off as I walked.

The good news is that they just needed a little breaking in. After about a day, they were molded to my feet just perfectly.  A sizing note. I usually wear 7 shoes but got 8 slippers and they fit nicely.  I wear thick merino wool socks with the slippers and they molded to my feet *with* the socks on. Now if I don't wear the socks, the slippers feel too big and do not keep my feet warm.

These slippers are in fact VERY comfortable.  Super duper comfy once they're broken in.  Since getting them, I wear them every single minute I'm at home. The rubber sole is nice for when I have to step outside in the yard and such. These are so comfortable that I actually forgot to switch them for regular shoes when I was going out once.

The first downside is that these slippers are NOT breathable at all.  Before getting these slippers, I wore merino wool socks practically 24/7, except in very hot weather.  My feet have a tendency to be cold all the time.  After getting these slippers, I still wore my wool socks 24/7.  A lot of reviewers have said wearing the slippers with socks was too hot for them, but not for me. Without socks, I don't find that these slippers keep my feet warm enough.  I don't mind that too much, but for $50, I expect slippers that are breathable.  By the end of every night, when I took the slippers off to go to bed, my feet would be sweating.

The fact that they are not breathable alone made me think that while they are indeed very cozy, I would not spend that much money for another pair in the future.  I would have given it 4 stars and not really bothered to have written this review.

Tonight, much to my disappointment, I noticed the side of the rubber sole, just under the seam has split and there is now about a 1-inch hole where I can see the cushioned insole inside.  I've only had these slippers for about 6 months!  I knew I'd have to get new slippers eventually but so soon?  For the near exorbitant price, I expected more than this.  Hence the 2 stars.  Next time I'll try Acorn. They've gotten positive reviews as well but are about half the price.
