Because Nike is all futures, all the new products you saw in the specialty store were confirmed last year. No one can 100% guess what will be sold next year, and what can't be bought will be cleaned up at the sale.

The reason is that getting the money back quickly is much better than staying in the warehouse for a year, and some of them are easier to sell but have broken the number. Moreover, the samples are generally dirty, and clothes are generally harder than shoes because of the strong seasonality.

The above is for reference, remember to adopt it ~
