Original owner. I've worn all of these, some more than others, but they all are still in very good shape. The most wear is on the pair with the red straps, with the footbed having more, but of course one doesn't see that part while wearing. In any event, I have developed foot issues that preclude me from wearing flip flops. I have washed these and run disinfecting wipes over them. Shipping from my immaculate home with 24/7 air purifiers. No smoke or other odors, and no animals inside or out.
