I just got these slippers; I need them for a halloween costume, but I love ballet slippers anyways so I'll wear them a lot at home.  The price was perfect ($4.75 in Oct 2012), and they're well made.  There's a tiny bit of cushion in the "sole" of the shoe, and they have little non-slip dots underneath to prevent sliding on hardwood floors.  They're very soft and satiny, and a really nice vibrant red color, and I love the cute little travel pouch they come with.  The "toe" area of the slipper is very short, so if you don't like the base of your toes showing, then these aren't for you.  It's a slipper though, and I don't care about my toes showing, and they were less than $5, so I'm thoroughly pleased.

A note on the sizing- you'll want to order big.  My feet are 8.5 inches along the bottom (according to Amazon, a size 5, and the Small slippers should fit size 5-6), and these JUST fit perfectly.  If my foot were half an inch longer, then my toes would be shoved into the seam up front, and it would be very uncomfortable.  I also have extremely wide feet, and these are accommodating, but don't have that weird "wide" look, so they would fit narrow feet as well.  I'd order them again, and if they're this cheap when my slippers need replacing, I'll get a few of these.  :)
