Question: What are the sizes of these slippers?
Document: We don't require that our guests remove their shoes before entering our home, but we have many friends who do it as a courtesy. I purchased the slippers and holder for those who may not want to walk around in their socks, or with bare feet. I was impressed by their quality, given the bargain price. The slippers come in assorted sizes, and the holder has a riveted hole for hanging.
I wanted inexpensive but cute slippers to offer guests staying at my home. This are very nice for the cost. They come in different sizes and colors so I had some for adults and pre-teens. The holder is really ingenious because it is also a slipper. These slippers aren't meant for heavy-duty use and they are slippery on wood floors, but they're good in a pinch for guests.
The product is as expected but it would have been better if they were diferent sizes to meet the needs of the guest.
Cheap for a guest slipper set, nice set of sizes, but the fuzzy bottoms mean they're rather slippery on hard floors. Considering the price and occasional use it's acceptable if less than ideal.
Plus, my husband, who wears a size 11 or 12, can't fit in any of them - so that rules out any male who enters the house with this average shoe size :\ I thought they came in different sizes, but alas, this is not the case. They're all about a women's size 8.
Very flimsy slippers. They have no sole, therefore feel super cheap. AVOID using on hard floors unless you like the feeling of ice skating around your house.
These slippers have arch support and a great feel and fit. I love the hard sole so I can pop outside if I need to.They support the feet, They are very comfortable and cozy. These are perfect and washable.I would buy them again and am happy with my purchase.
I have been searching everywhere for slippers after my visit to Japan where no one wears their street shoes in their homes. These are cute and will be nice to present to my guests when I get confident enough to request people to take off their shoes! I often scrub my floors by hand and just cringe when people walk in. I have a friend who has a white rug and she has a sign by her door to please remove shoes with a basket of mixed slippers.
There is one pair of red slippers, one pair of beige, two pair of black and two pair of grey slippers. They appear to be made of felt like they use in the museums. The holder is very cute with an embroidered men&#34;s shoe of two tone black and white and next to it a woman's red high heel with black tip. I am happy with this purchase. Now I need to make a sign.
Eh, not quite what I was expecting. I was so excited to finally find a set of house guest slippers, because my house has a no-shoe policy and guests are often asking to borrow socks or slippers. I thought this would be so nice to offer in my house's entrance foyer. But the felt makes your feet sweat in tepid temps, and I don't feel safe walking in them on my hard floors because there's no grip on the bottom - it's just wool felt.
