1. System problems caused the payment to fail. If you pay immediately after the order is confirmed, but the payment method such as Alipay or credit card fails to be automatically deducted successfully, your order status will be displayed as "Confirmed but not paid".

2. The order has been suspended or the product has been cancelled. If after confirming the order, the Nike platform finds that the product has been sold out, canceled or cannot be shipped for other reasons, the order will also appear as confirmed but not paid.
