Dunk black and white panda shoes have yellow tongues.

Dunk's black-and-white panda's tongue may turn yellow for the following reasons:

1. After cleaning, it was yellowed by the sun. Because the soapy water or washing powder water in the vamp is not thoroughly cleaned after washing shoes, the concentration of soapy water and washing powder water increases after sunlight evaporates water, which leads to the yellowing and hardening of shoes.

2. Because the crystal bottom of shoes or other transparent materials will turn yellow, this is because shoes have an oxidation reaction when they contact air and water.

In either case, you can try cleaning with detergent, or cover your tongue with toilet paper, or soak it in white vinegar. However, it is necessary to avoid direct sunlight and keep shoes dry, which can prolong the service life of shoes.
