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)

Extremely comfortable, leather sole. Hard to find a style.
Size: 13.5-14.5 Women/12-13 Men, Color: Navy Blue, Size: 13.5-14.5 Women/12-13 Men, Color: Navy Blue
Totally worth the price. This type of style is very hard to find, my husband had another pair a few years ago that he was never able to replace. These fit his wide feet and are very comfortable. The elastic at the ankle is not too tight. So glad I was able to find him a replacement. We bought the blue in a size 12. Love the fact that they are washable.

Very comfortable Slippers. Great buy!
Size: 12-13 Women/10.5-11.5 Men, Color: Charcoal
I bought these to replace a pair of slippers that I have had for years that are very similar to the slippers I bought, but I had worn a hole in the leather on mine, so I had to find something new and similar. These slippers are worth the money they are very comfortable, and I am sure they will last for years. They are a little tight around the ankle cuff but they are still new and I am sure they will wear in a little more when I start wearing them more.

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?
