For cute, stylish and comfortable I would reccomend either the TEVA "Dozer" sandals:
or the Merrell "MJ Encore"
I walked all throughout Disneyworld this past Spring in the TEVAs. They were very comfortable, light, and airy! I don't have experience with the MJ by Merrells but I have several other pairs and love them.
If you find something else let us know, I'm always looking for new additions to my shoe collection!
