Toss in the wash with cold water. Air dry. Boom.
Love the look, not the fit
"I’ll start off by saying I had high hopes as a big Rothy’s fan. The look of these is excellent. The revelvet material is also very cool and looks and feels like it will wear well. The downside - these gave me blisters on my heels after wearing only a few hours. It’s possible they will break in, but not having a break in period is a big reason why I love the older cloth Rothy’s shoes. Bummed to say the least."
