Speaking of shoes

Ok- I have this thing about shoes, I want something pretty, but easy on the feet. I went to a wedding last summer and I was miserable because of uncomfortable shoes.

I'm probably going to get flips flops anyway, but I want something comfortable for at least the first part of the wedding.

What websites have good shoes? I've looked at myglassslipper.com, zappos.com, and shoes.com and I didn't see anything that grabbed me.
