I got the violet color, and they are beautiful.  The material is very soft, and I am happy to slip into them each day, despite their shortcomings (details to follow).  My feet \\"officially\\" measure at about an 8 or 8.5 wide, but as a shoe salesman recently pointed out to me, that's meaningless (unfortunately).  I was previously wearing a size 9 tennis shoe, and when I bought shoes most recently, I got a 10 (even though my feet haven't actually changed in size.  I ordered these in XL (9.5-10), and they fit just fine.  I like that they stay on easily, but aren't too snug.  According to a shoe sizer, these run small.  But judging by my latest shoes, they are true to size.  Amazon does offer free exchanges on these (depending on size and color), so you could always send them back if they don't fit.  If in doubt, order a size up.<br /><br />Despite their charms, there are a few issues.  One is that the inside lining of the sole is stitched in place with clear plastic thread, which I find to be a little uncomfortable.  Over time, this kind of mashes in, but I think Isotoner should consider an alternate form of attachment.<br /><br />My biggest complaint is that I wish the soles were much thicker.  Looking at the picture, they look thick, but that's just an extension of the sole wrapping onto the upper for durability.  The sole itself is pretty thin; these don't offer much padding against our hardwood floors.  I had to use double-sided carpet tape to secure shoe inserts in these to make them usable for my needs.  That's worked okay for me for now, but I will be on the hunt for slippers with thicker soles.
