This is a pair of soft and comfortable slippers. They look like suede slippers but are made of cotton and synthetic materials. It is well-made and comfortably cushioned with a memory foam insole. My feet get cold easily, so these are great for wearing around the house especially where it isn't carpeted. It has a textured, non-slip bottom outsole to provide some grip on surfaces. In terms of sizing, I selected size US8-9-10 from the drop down menu on the Amazon page, and the tag on the insole says UK 7-8 / EUR 40-42 / US 9/10. I am a womens US size 9 and it fit me just right in terms of the length, although it was just a little loose fitting for me as I have low volume narrow feet.
