I washed a pair yesterday, and they came out looking brand new! (Tip-- take any Jibitz out first.)
Do not put Crocs in the dryer!
Here's a bonus $ tip isn't for everyone.... POTTY TRAIN!
I have one who has been less than willing, but we went after it over the last two weeks. By going ahead and being consistent and persistent with training, we can now save $20/week by not buying diapers!
