I know what you're talking about. Rainbow Macy's exclusive color scheme. But I don't recommend you to buy it. F 10 is the worst mid-range shoes. F50 series is famous for its speed boots, but its lightness is only reflected in high-grade shoes, low-end, middle-end and rubbish. The price of shoes you mentioned in Taobao is about 400. You can spend more money to buy some other series of top or sub-top sports shoes.
