I will update my review if any other issues arise. Not the sellers fault but, the delivery driver didnt follow special instructions and dropped it wherever he felt like. Took me a few days before I discovered the source of the rancid smell coming from my son’s room. Returned these immediately! We can do better elsewhere! The wood insoles make you feel as though you are walking on rocks. And there is no return also. I didnt struggle with the straps wanting to tighten over time either. For stony beaches - not so much. The slippers are soft and comfortable.
