I bought these for my 3.5 year old, princess-loving daughter for Christmas.  She was so excited when she opened them and said "Mommy, these slippers are soooo beautiful!!"  A huge hit, and they're super cute.  She put them on right away and wears them around the house all the time.  They seem like they'll be durable.

Seem to run a little small so I'm glad I ordered a size larger than I normally would get.  The only downsides I can see (nothing too major) is there's not much traction on the sole and we have wood floors so she slips around a little bit; and another thing is due to the packaging the part where the heel meets the boot have sort of a kink in them, which just makes it awkward for my daughter to put them on correctly herself.  I have to help her or she can't get them pulled on all the way.  Not a huge deal but just slightly annoying.

Overall, a great choice though.  If your little one loves Disney princesses, then she'll just adore these slippers.
