I Love these noisy shoes.  Yes Noisy!  Although they are very comfy and I enjoy wearing them around the house, I rarely wear them anywhere outside the house because of the noise they make.  I'm not sure why they squeak, I can't even really call it a squeak because that sounds cute, but as you walk it lets out a low squawk with each step.  I think it's due to the insert rubbing on the bottom of the shoe on the inside.  So, if you don't mind making noise while you walk get a pair of these and make sure you go someplace noisy (not a library, church or school).
