First of all, if they are genuine shoes, they are currently being discounted in major supermarkets. Of course it's the old one. If you want to buy a new model, just look online and there are new purchases. The general purchase price is about 20% off.
Haha, there are also more than 20% off.
If it is reverse shoes, it depends on the price. At present, there are anti-shoes on any road of Sports Institute Road and Guangba Road, and the price is fairly cheap.
If you are interested, you can go to my friend's shop, in the south gate of China Normal University, the "match point" shop selling anti-shoes.
My friend's anti-shoes are ordered directly from the manufacturer, and the quality is much better than what I said about Tiyuan Road and Guangba Road. You can go and have a look and compare.
