The usage method is simple and convenient. Open the packaging box, choose the appropriate shoe size according to the size of the shoe, place the product head down on the toe, and slowly put the tail over the heel. After adjusting the position, press the power button in the middle to light up. There are three cycling modes to choose from: fast flash, slow flash, and constant light. When the shoe cover runs out of power, you can take out the power box at the back, open it, and take out the internal battery. Replace it with a new battery to continue using it.
