Toss in the wash with cold water. Air dry. Boom.
My new Favorites!
"I am a Birkenstock girl through and through but since I bought these, i reach for them every time. They are more comfortable than you can imagine.. and SO CUTE on. I haven't washed them yet, hoping they hold when I do. Already looking for my next pair. I wear 8.5/9 in most shoes and a 9 fit perfect with a little room so my heal doesn't hit the edge. Love the tortoise sole and blue stitching on the heel."
