Great slippers but disappointing quality.
Size: 7.5-8.5 Women/6-7 Men, Color: Ash, Size: 7.5-8.5 Women/6-7 Men, Color: Ash
Extremely comfortable, attractive slippers but the stitching came loose on both leather trim areas almost immediately. I tried to sew/glue down the stitching (as seen in photo) but it kept unraveling. Disappointing as these slippers are great in every other way (though they do run a bit big...I wear a 9 but ended up with a 7.5-8.5 which fits with a bit of room to spare even with thick socks). I just hope they hold up after my latest attempt to stop the thread from pulling out any more as I do really love wearing them. Perhaps I just got a bum pair?

Quality and comfort
Size: 10.5-11.5 Women/9-10 Men, Color: Black
Comfortable and fit well. I got these to replace a very old pair that finally wore out! Warmth is medium (I wear puffer booties for when it's really cold). Quality on these is great!

Can't go wrong with Acorn for as long as they last!
Size: 12-13 Women/10.5-11.5 Men, Color: Charcoal
Acorn is just a great company all around. I had bought my husband these slippers over 20 years ago. They are still in great shape although the sole has worn in some places. But nothing's coming apart! However, I decided to replace them for him. His foot is 10.5 and they are a little hard to get on right away-of course, after over 20 years of having "worn in" the original pair, anything would feel tight. So I'm not holding this against them. They will relax with use. The only difference is that the original sole was black and these are tan. I think I would prefer the black, but since it's only being worn in the house, no big deal. My husband has really cold feet and these slippers never fail to warm his feet right up! He said they feel really soft to walk in and like the cushioning. They're not too heavy and fit him great! I have Acorn slippers myself that I've worn every single day in the house and outside to the mailbox too. They last.

You won't be sorry
Size: 10.5-11.5 Women/9-10 Men, Color: Black
Great padding for comfort and terrific warmth. I bought a pair of Acorns 30 years ago and still have them. Updated to a new color and now feel the benefit of newer padding! I used the sizing listed for shoes and like the roominess for thicker sox. Well made and a joy to put on. (Wisconsin)
