I was pleasantly surprised that the slippers fit my feet nicely. I have wide feet and they slipped right on with no tugging. The package says they fit a women's size 6 to 9. I'm an 8 1/2 and they do seem to have enough room left for a size 9 foot, but definitely not any more. Women with larger feet are out of luck, unless they can find a bigger pair somewhere.
The slippers are quite comfortable. The microfiber on the bottom of the Slipper Genie provides a cushion and even feels supportive.
This is a picture of the mircrofiber on the bottom of the Slipper Genie. This is actually attached to the bottom of the slipper with heavy-duty Velcro. I'm assuming this is so the wearer can remove the microfiber and wash it, though the package does not give washing instructions.
I have a dog and a cat, so we've got fur on our floor, no matter how much I sweep and vacuum. Since I don't do either of those things often enough, there is no shortage of fur and dust for the Slipper Genie to collect. Therefore, I was slightly disappointed at how little fur I saw trapped in the microfiber. I expected more.
If you are looking for an effective floor cleaner, don't trade your Swiffer in for a pair of Slipper Genies. However, if you just want a pair of comfortable slippers that will pick up a little bit of dog hair and dust at the same time, then the Slipper Genie isn't a bad investment. You'll still have to clean your floors the old-fashioned way, but at least your feet will be cozy.
