Just got these and the whole heel came off of one of the shoes the 2nd time I wore them. Fit fell but unfortunately broke, disappointed because I really liked them.

Ex Input:
This book has a interesting storyline but I found this book about as much fun to read as a textbook. Reading it was like slogging through a bog - it just didn't flow. If lack of proper punctuation and misuse of words (their for they're, your for you're, etc.) annoys you, don't bother with this book. I did persist until the end because I wanted to see how it played out. Guess what? There is no end. Everything is left up in the air, nothing is resolved! Ugh!

Foam is flaking off and comes through material on top and leaves a residue on top of chairs. Can not even get it off with a lint brush. Very unsatisfied.
