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?

Do not buy these
Color: Nude, Size: Women 9-13
These are terrible. They are designed to walk in. The first day I tried them on I walked about 20 steps and they basically ripped right off my feet. I didn’t think much of it and just thought ok I won’t walk in them I’ll just wear them to bed. The second pair that came with the order I wore to bed that night and woke up with holes tore in them. Terrible product

These are form-fitting and durable. Wearing these keeps the skin moisturizer in place so it can be effective.

Great Results
Color: White, Size: Women 9-13, Color: White, Size: Women 9-13
The Jfrhuds Moisturizing Silicone Socks work very well. I ordered the white 2-pack in the large size 9-13, and each came packaged in an individual zipper bag.  I wear a women's size 9-9.5, and they fit me perfectly.  I can see how they have enough stretch to fit larger sizes easily and comfortably. These socks are a lot thicker and heavier than I expected.  They are rubbery with non-slip treads on the bottom.  As soon as I put them on my feet, they actually felt very moisturizing and almost wet, even though I had not put moisturizer on my feet first.  Plus my feet felt cold at first. It was different than I expected, I had never worn this type of sock before, and it was an interesting sensation. They work great, and I am sold on the benefits of these socks.  I wear them to sleep at night and dodn't walk very far in them.  They seem pretty sturdy, but I don't want to push it and will just use them for their intended purpose.  My feet weren't super dry or cracked, but the socks really helped revive them and make them super soft again.  I love them; they are great for self-care and would also make a wonderful gift.
