I've been on the hunt for a great slipper for some time.  I have Rheumatoid arthritis and Lupus, and it has been affecting my feet terribly lately.  They hurt so bad, so I want to live in comfy slippers.  I felt this slipper was a bit pricey, but I was desperate to alleviate my foot pain, so I bought them.  THEY ARE WORTH EVERY PENNY!
This slipper is true to size.  I am a solid size 9; that is what I bought and it fits perfectly.  I can't wear it with a thick wool sock, but I can wear it without socks or with a thinner wool sock.  It felt a little tight at first, but after I wore it just a few times it fit to my foot perfectly.
They aren't the cutest slipper, but they are nice enough, and the flowers are a nice little touch.  The foot bed is sculpted so nice. My foot slips right in and stays put.  The shape of the slipper is great, too - just enough room for my toes.  It totally cradles my foot and provides wonderful supportive cushion.
I've had them for over a month and have washed them a few times and they've held up perfectly.
I never thought I would love a slipper so much until I had arthritic feet.  I will surely buy another pair when needed, and recommend you don't think twice about this slipper!
