Soft, Warm and Cozy
I have no idea how these stay up, probably magic. I'm tall so it's challenging to find boot style slippers that are long enough. If support or thick soles aren't an issue, these are the best I've ever found! My ankles and calves have never BEEN so warm; these are my go-to's in the evening. They're easier to walk in with socks but, without, they're floppy and loose. I'd hesitate to size down because it's more the lack of structure in the foot, not length. They wash well (air dry); still soft, warm and cozy. Inserts could probably be added to help with support. I tried them because I found them at a fantastic sale price but I'm buying another pair now, for winter. I'm a slipper person and I definitely notice the quality of materials in Acorns, when I compare them with other slippers.

My year round footwear
Size: 6.5-7.5, Color: Sunset Cable Knit
I literally LIVE in these "slippers". Inside, summer, winter, outside when I can. I have hardwood floors, so even summertime, they protect my feet. They give me enough cush, but not like structured slippers that feel more like shoes. I go through about 2-3 a year, but well worth it.

Weird sizing
Size: 5-6, Color: Charcoal
Weird sizing/ fit! It says that they run large in length, so I got one group-size down (5-6). (The sizes are in ranges rather than specific individual shoe size numbers). I liked the concept of the suede reinforced toe & heel for longevity. My heel and toes cleared the length/width comfortably/well and the overall width was more than adequate, yet I found them to be rigid-stiff- tight (to the point of cutting off circulation) specifically in the toe. Ok, I knew that was a possibility BUT……while the toe area was tight the ankle and calf were HUGE and would not stay up unless I wore over pants, defeating the purpose of a slipper-sock. The inside cushioning was soft and comfortable. When I walked, my heel would slip out over the sued area, into the wool sock parentheses, making it awkward to walk. Returning…No point in changing sixes, as if I get a larger foot size, the tow may fit better, but the ankle will be beyond too big. Sigh. Unfortunate, as the concept is sound….the manufacturing/sizing is bizarre. BTW : I have normal width feet (not wide or narrow) and my ankles and calves are on the thinner side. The fit may be better suited to people with wider ankles/calves????

So cute
Size: 8-9, Color: Charcoal Faux Fur
These boot slippers are super cute and comfy warm. Fit true to size. Inside is real soft and warm. No, they do not offer support....they are slippers after all. The fur does not go all the way around the back. The back is just the woven sweater material but I imagine they would have zero stretch if the fur went all the way around. It may not be as cute without fur all the way but they probably wouldn't stay up if they didn't have the stretch material in the back so your only choice would be to let them slouch. I can pull them all the way up and they stay, I can do any degree of slouch and they stay so I see this feature as purely functional. Love the 2 tone with the suede around the toe and bottom but this is where my only complaint comes in is the sweater material right above the suede toe looks puffy so that part looks a little silly but otherwise they are absolutely adorable, comfy, warm and as functional as a pair of slippers can be. I wore them out in light rain and my feet stayed dry. The bottoms are like a rubberized fabric so they may soak through if you're in constant wet. Traction is surprisingly good even though it doesn't have a lot of tread. Overall i love them.

The answer to calloused feet.
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
If you have dry callused soles, these are your answer. All my calluses left and my feet were very soft. They should not be walked in unless you are very, very careful as you will slip and fall. I stopped using them for a while and all my problem calluses are back, even when I use lotion at night. They tell you not to sleep in them, I don't know why. I do put these on at night and end up taking them off later as they're not comfortable to sleep in.
