Georgia Comfort Core Five CC5 Insole

The Georgia Comfort Core Five (CC5) removable insoles are designed with ergonomic arch support for a fit that is both supportive and incredibly cushioning. Foot fatigue is a thing of the past when you add these inserts to your favorite pair of boots, thanks to special airflow channels located on the bottom of the insoles; they push air toward your foot bed with every step you take, so that you stay cool and relaxed no matter what is next on your list to tackle.
