I allways have a pair of Lazy Boys in the closet that I use all the time ( like a pair of favorite jeans ) and they seam to last for ever but , last year I read about these sandals that were made of yoga mat material and decided to buy a pair well, those were the THE MOST COMFORTABLE SANDALS EVER ! they are just squishy soft and even more comfy that the Lazy Boys. But like all things they don't last for ever. Last years pair only lasted 4 months , I guess my 205 pounds didn't help ! I also purchased several pair for the kids , theirs are still good .
