I've been wearing a pair of these for almost a year now.  They're the first pair of slip-ons I've Had since I was a child.

Out of the box, the first pair delivered had a loud squeegy sounding squeek with every step coming from my left shoe.  I requested a replacement pair and one was promptly sent to me.  After about 9 months,the left shoe again developed a loud squeek with each step. At 12 months the right shoe developed a loud squeek with each step. I believe there is a manufacturing issue with the way this shoe is made.  I would not buy another pair.
