Toss in the wash with cold water. Air dry. Boom.
Cute but not comfortable
"This is my first time wearing this style of Rothy's shoes. I have soooo many others and this pair is super cute but NOT IT. They are not comfortable and slip off the back of your heels badly. My feet feel cramped from having to keep this style from not flying off. I originally got a 7.5 and exchanged them for a 7. Both sizes slip off my feet. Not my fave pair of Rothy's, but I absolutely love Rothy's in general."
