Topup Insole / Insole

Topup Insole

We have all experienced the embarrassment when the sand go into shoes when doing outdoor activities. Considering personal image, many people would rather bear the discomfort than take off shoes in public.
"Topup insole" can let you get rid of the trouble. The front end of the insole is designed to store the sand in a "special room” between the insole and toe cap by upturning a certain degree. Once the sand go into your shoes, you just need to hit the ground with the toe cap to let it slip into the "room" and it will be trapped inside. The upturning front of insole will block the sand and keep it away to avoid discomfort in your walking.
