I suddenly needed to go somewhere I couldn't wear sandals, so I bought these on the spot as a temporary measure! I only wore them for a few dozen minutes, and since I was wearing new socks instead of going barefoot, they are in very clean condition. (Please refrain from purchasing if you are concerned) I changed to different sandals immediately after buying them, so they are in near-new condition. There are no odors or stains. I only wore them temporarily out of necessity, so they are perfect for those who think, "New ones are expensive, but I want something in good condition!" *No box*
