I wonder how long it will be before it packs in altogether. Overall I LOVE these shoes Threw out the package so cant return. In fact, the liner is super easy to remove and presumably replace when/if it gets too worn or smelly. Materials feel sturdy enough to last and it was super easy to set up (less than 10 mins). They are fragile but most jewelry is so just be careful handling them-none of mine have rusted or broken yet and if they do I’d probably buy more I like them that much. Im extremely happy with my purchase and may just purchase another sooner than later. the ear pads are very nice feeling, with just the right amount of cushion. Im so happy I purchased it. I would definitely buy another pair with how comfortable they are
