I bought these Madden Girl boots for my wife. She wore them once and the heel on one of them gave in and broke the first day!

We figured we got a factory dud, since the heel on the other boot was intact, so we returned the pair to Amazon and they very quickly shipped us another pair. (Amazon's customer service is a 5 star).
The second pair faired better on their first use, but the second time she wore them, BOTH heels came off completely and she was leaving a trail of pieces of the heels while she walked.

Seeing how we're not the first to have the same experience according to other reviews, I really think there's serious quality issues with these boots, which is a big shame since my wife really liked how they looked.
