The overall quality of the product is satisfactory (for a Chinese made product); however, the slippers are difficult to retain on the foot. Moving forward is okay. Take a step backwards and you are barefoot. I should have known from the picture of the slippers that they were designed to "slide and glide," not walk.
This is a well made fleece slipper and a good value. The soles are also a bit thicker than comparable brands. As long as it's dry, you'd be perfectly safe wearing them to take the dog out or get the mail. One caveat: if you have narrow feet (I don't), you might find them a bit wide without socks.
