Ugg boots are known for their warmth, comfort, reliability and the quality materials with which they are made. The boots have become increasingly popular since their introduction, and for good reason, but some consumers complain of the lack of arch support in the boots' soles. Unfortunately, no Ugg boot models come with arch support, but you can boost the comfort level of your current boots by adding your own arch support insole at home.
Items you will need
Insoles with arch support
Sharp utility knife
Shoe-bonding adhesive, such as Shoe GOO
Fold down the tops of your Ugg boots to more easily reach the inside bottom of them. The more you fold the better, as this gives you more visibility while working on this project.
Use a utility knife to cut a "C" in the heel of the insole, along the sides and back of the boot. Cut lightly and don't cut through the outer material of the boot.
Use the edge of the knife to peel back the heel of the boot's insole. Don't tear the fabric or any other material as you pull away. Do not separate the material completely from the inside of the boot. Use a shoehorn or similar object to separate the lining from the bottom of the boot without tearing it open.
Slide the insole with arch support into the boot between the lower lining and the sole. Use a small amount of adhesive to hold the insole to the floor of the boot.
Use adhesive liberally on the underside of the heel material that was cut away initially and replace it. Place a heavy object in the boot and allow the adhesive to set for 24 hours before wearing your Ugg boots for any extended period.
