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.

Picky dog approved!
Color: S6-muti-color, Color: S6-muti-color
I have wasted so much money on dog balls that they won't even pick up! They finally were obsessed with the Kong rubber green/blue or red/blue ones, but they're $3+. each, and they break from the dogs squishing it. I honestly had zero expectations on these, and they BOTH picked them up on the first throw! That's huge!!
Seem to work fine in the ChuckIt.
As for the squeaker, at first I was like "Oh nooooo." when they both loudly started! Much to my (and my neighbors') happiness, the squeakers stopped working after a couple minutes. 🤣

Durable
Color: S6-muti-color
The balls are great for chewers. The squeaky didn’t last long but they are perfect for the ball launcher.
