Stopping production of shoes may be an alternative. From a commercial point of view, the suspension of production of a product represents the limit and limitation, which may also indicate that the product is not performing well, the sales volume is insufficient, or it is defective or seriously injured. It is also possible that the old model has a high cost, in order to reduce the cost. Under normal circumstances, shoes that have been discontinued are not available in the market, and the things purchased are not necessarily genuine.
