Toss in the wash with cold water. Air dry. Boom.
Not worth the hype
"I purchased my first pair of Rothy’s. You’re supposed to buy a half size up because the shoes will shrink. That concept made me nervous, so I went with it. I decided to wear them out of the store to finish my shopping. The shoes severely cut into the back of my ankles, and had to buy bandaids at a local shop. Once I added on a heel cushion, I was able to wear them again. I like the idea of utilizing recycle plastic, but this is not for me. They are not very comfortable either. i think they run narrow. Would not buy again. It is not how I want to utilize my money."
