Toss in the wash with cold water. Air dry. Boom.
Great new style !
"I bought these to wear with a compression sock on a long haul flight. I’m a 6 1/2 and the size 6 was perfect but perhaps a bit too small to wear with any thing but the thinnest sock . I loved them though, so i bought another pair in a 7 to wear with socks and they’re also perfect . The penny design is much narrower than the old style clogs and so work better for me."
