Great slippers made very well for a great price!
Size: 10.5-11 Women/10-10.5 Men, Color: Black
I am in love with these cat slippers. Part of me thought they wouldn't be of good quality but when they arrived I was pleasantly surprised! The sole on these slippers is strong and sturdy which was one of the main reasons I purchased these. Prior to owning these I had a different pair of slippers that had a soft sole, every time it would rain my feet would get soggy with these slippers I don't have that problem. The cute cats were the other reasons for purchase, they are just so cute! The stitching on them seems to be sturdy and very well done. AND the best part, THE SIZE RANGE! I am a women with rather large feet, size 12 in women's to be exact. I can never find cute feminine slippers in my size but these not only have my size but they were actually true to size and fit!

Runs a bit small
Size: 8-9 Women/7.5-8 Men, Color: Black
I absolutely LOVE these slippers. They are very comfortable. I would suggest going up a size when ordering. I normally wear a ladies 7 or 8 in shoes (pending how the shoe is made). I ordered these in the sizes 8-9 category and I'm glad I did. They fit just right, so I think the sizing is a bit off. I love the soles on the bottom as well. I feel like I have finally found a great pair of house slippers...and they're CUTE!!!

Order one size up! Cute & cozy slippers
Size: 8-9 Women/7.5-8 Men, Color: Pink Cat, Size: 8-9 Women/7.5-8 Men, Color: Pink Cat
The slippers arrived today ( I got the gray and pink ones) and they are adorable. They fit more like a 7.5 than an 8 or a size slightly smaller than what the usual medium would be so I’d recommend ordering one size up. They’re soft and warm. 10/10 for the designs and colors. The bottoms/ soles are a rubber like material but no complaints there. So far, I’d buy another pair.

Amazing
Size: 7.5-8.5 Women/6-7 Men, Color: Khaki
These slides are so good! First off, the price is insanely good for such great, long lasting slippers! I ordered the khaki color and it was a nice tan color that elevates every look, whether comfy or more casual. These are so comfortable and also flexible but without breaking which is amazing! The material is soft and perfect for everyone.
