The light-up shoes have a large battery capacity and can last a long time.

Because the shoes are not USB-connected, they are powered by a battery in the sole. Sometimes, due to the battery's charge, the light may not work, or one light may be bright while the other is not, or one may be bright while the other is dim. All of these are normal. If there are issues with the light, such as one side being brighter or darker than the other, or if one light is brighter or darker than the other, or if the color is not even, we do not consider these as quality issues. People who are sensitive to these issues should be cautious when purchasing!
