Toss in the wash with cold water. Air dry. Boom.
Love the shoe!
"This was my first pair of Rothy's. The recommedation was to size down. I did and was pleasantly surprised that the length was great. After a full day of wearing, I felt that the toe box was a little tight. I will continue to wear them. If they become more comfortable, I will probably order another pair, different style and in my normal size. I love everything else about them!"
