The phrase refers to previously owned Nike Air Max 90 sneakers. These athletic shoes, known for their distinctive design and visible Air cushioning, have been circulated in the secondary market after initial purchase and use. An example would be finding a pair offered for sale on a resale website after the original owner no longer wants them.
Acquiring these pre-owned items offers a more budget-friendly option compared to buying them brand new. It can also represent a more sustainable choice by extending the lifespan of a product and reducing demand for new production. Furthermore, the vintage market allows individuals to obtain discontinued colorways or limited-edition releases no longer available at retail.
