Toss in the wash with cold water. Air dry. Boom.
Love them
"These are my favorite pair of Rothy's and honestly, shoes in general, for everything: lounging around the house, errands, work. I don't care, they come everywhere. They wear like a slipper. Go a full size up! I tried to stick to the half size up but it was too tight around the toe box. I also like to wear thin socks with them but even barefoot half size up was not enough. They're so easy to slip on you'll feel like you're not wearing shoes. If you want something comfortable and low volume, GET THESE!!"
