Maria, I saw your post about the Dundan's back in February and have been pining for a pair ever since.
I can't wait for them to go back on sale in the fall.
I just received a pair of Vivo Barefoot Lucys and I think they're great. They're black leather with a little bit of red (for the logo) so are very inconspicuous. I'm looking forward to trying them out outside with socks on when the weather turns cooler. I've walked around the house with them a bit today and find them extremely comfortable and kind of slipper-like. I'll post more about them after I wear them a bit more. They just arrived yesterday so I don't have too much to say about them yet but my first impressions are very positive.
