I wish that these inserts had an adhesive so that they could stay put in my Ugg slippers.I love the liners in my boots where you can pull out the original one and replace it with the liner. The liner doesn't work well in Ugg slippers because there's no liner to pull out. I loved how they felt when I first put them in my slippers however when I walk around the liners slide backwards. I would give them 5 stars for my Ugg boots but 1 star for Ugg slippers so I gave them a 3.
