Toss in the wash with cold water. Air dry. Boom.
Obsessed
"I wanted these for sooo long but I hardly find stuff like this comfortable. Somehow these are soooo comfy and I’m in love with them. Worth every penny, I wear them daily & plan to get more colors. I’m usually a 7-8 7. 5 tends to be perfect and I first I tried a 7 and it worked my foot off but it felt just exact at the heel vs. the 8 is most comfy and fits with socks as well but doesn’t feel huge. So if you’re in between and feel the smaller size would be tight. Go the other way!"
