Toss in the wash with cold water. Air dry. Boom.
So comfortable!
"I love these shoes so much! I do wish I had ordered one whole size up instead of just a half. Unfortunately I’ve worn them and thrown away the box already so I can’t return them. Would be more comfortable if they were the correct size but I feel I could wear these for hours. Only issue is where it rubs from my toes scrunching on one foot. Order these, they’re amazing."
