Since I had nothing to lose, I threw them in my washing machine with a few old towels - and was VERY pleased to have them come out sparkling clean. I like the substantial sole on them as well. I know I gave it 4 stars but that?s because don?t ever give 5 stars, but I was very close to doing so. "Light the starts. Overall good quality for the price. I needed a nude slip to go under a sheer white maxi dress and this was perfect! ) My daughter introduced me to Classic Crocs this past summer, and they were SOOOOO comfortable, I decided to invest in a prettier pair, but ones I can wear year round, (enclosed heel, no slots in the toebox area. So far they are holding up very well, and she wears them every day. Fortunately a long-time Birkenstock wearing friend was there when I unpacked mine and pointed this out. Despite this, theyre rugged as hell.
