The short answer is yes with a little bit of no. You can save money by buying last year’s or the year before’s shoe models. There’s nothing wrong with that except that shoe materials have a shelf life. The cushioning foams and support structures start to lose their integrity even if the sneakers are sitting on the shelf unused. It can potentially shorten shoe life by a few runs. If you buy an older pair of sneakers, be on the lookout for signs of wear earlier than if you bought the latest model.
