Shoe dog is a name for people who like to collect shoes. There are many shoes at home, and the shoes and dogs are all named by themselves. In fact, just as girls like to collect bags and lipsticks, boys also have a soft spot for shoes. With the tight and high-priced sales of sneakers, in recent years, classic sneakers, such as the new Apple mobile phone, have been snapped up by consumers as soon as they are listed. The story of queuing all night, buying shoes by lottery, and reselling at high prices is becoming more and more fascinating.
