Nike full palm air cushion shoes leak, how to repair them? Urgent!

One: the air cushion is useless if it is broken, and there is no way to repair it. If you find the invoice, you can try it at the counter where you bought it. Just say that the air cushion is leaking because of quality problems and ask him to change it. But I think it is more likely to damage the air cushion artificially, and less likely to replace it. After all, there is almost no possibility that the air cushion will break down due to quality reasons (the transparent thin layer is actually very strong).

Two: air cushion shoes can be mended if they are leaked. Stick a small piece of mobile phone soft cover on the leaking place with shoes, and inflate it after gluing. Methods: Punch the scalp needle into the shoe for transfusion (choose the appropriate position), then inflate it with a 20ml syringe, and finally inject about 0.5 ml of 502 glue with a 1ml syringe according to your shoes, and keep it for one hour, then cut off the exposed part and drop a drop of 502 on the needle.
