Nike generally uses high-quality materials to make their Air Max lineage. They use durable materials that could add to the longevity of the sneakers, which means they ask consumers to pay for a shoe that will perform better and last for years compared to the cheaper alternative.

Sizing & Fit: The Air Max 90 runs more on the narrow side so you have to be mindful if you have a wide foot. In my personal experience, the Air Max 90 runs true to size. If you have a wide foot you might find them a little tight, I suggest going half size up for some extra room.

Every pair of authentic Nike shoes comes with an SKU number that is identical to the SKU number on their box. If the numbers are missing or do not match, they are likely fakes. Check the tongue label. Often, fake Nike manufacturers put outdated sizing labels on the inside of the shoe.
