1. Filling method: Fill the soles with clean and soft materials (such as newspapers, towels, cloth, etc.). Adjust the quantity and position of fillers appropriately, so that the sole can gradually return to its original shape. Then, put the shoes in a ventilated place to dry for a period of time.
2. Hot water method: Soak the jelly sole in hot water for a period of time to soften the material. Then, take out the sole and press it back to its original shape. Be careful not to get burned. You can protect your hands with thick gloves or towels. Finally, dry the shoes.
3. Blower method: Adjust the blower to medium-low temperature, and perform hot air blowing heat treatment on the jelly sole. While blowing, gently press the shaped sole with your hands or other tools until it returns to its original state. Finally, let the shoes dry naturally. Please note that the above methods are for reference only, and the effect may be different due to different shoe materials and indentation degrees. Before trying these methods, it is recommended to test in an inconspicuous position to ensure that it will not have a negative impact on shoes. If you are not sure how to operate or worry about damaging your shoes, please consult a professional shoe repairer or manufacturer.
