Here's a bit about each pair:

Miranda's shoes: Antonio Melani gold-heeled sandals, size 9. They feature gold, silver and bronze straps. Miranda signed the inside of one shoe. Value: $89.

Taylor's shoes: Betsey Johnson black sandals, size 8. The bottoms of the shoes have a pink, rose-decorated background. Taylor signed the bottom of one shoe. They're valued at "priceless."
