Toss in the wash with cold water. Air dry. Boom.
Wish there was a half size
"Super cute shoes. The size 2 was too big (like slip off the heel big) and the size 1 was toe at the very tip, so to keep them on, went with the size 1. Heel rubs and not super comfy, but im sure that's only because there is no size that works well, if between sizes. Will likely size up and wear socks if we try again."
