I just bought these. They came today (free shipping) and I LOVE them.
I sometimes have trouble finding something I like on Zappos - I have to know exactly what I want (in this case, a black pump) and then go looking for it.
I will say this, though: for a wedding last April I had to have "white strappy heels", and Zappos was GREAT about returns. Didn't charge me a thing in shipping, and it took just two or three days.
(edited to specify I ordered one pair, they had pink trim, and I had to return them - NOT that I returned them after wearing them in the wedding. Ew.)
