I checked back in on the rainbow sandals today: they are sold out, but there's one review up. And it's a doozy.
Here's the text, in case you can't read it:
"The shoes are the best. I own many others, but these are def. my favorites. The bright multicolored heel make them an attractive option for any occasion/outfit. I wore them last weekend to my sister's wedding, and although my mother was horrified, and my sister was too self-absorbed to notice, my dad said they reminded him of the buttons he used to sport back in his "anti-man" hippie days. I only fell over once, but all the looks of jealousy made it worth it. Def a worthwhile buy. ENJOY!"
