Conclusion. What drives the retail markup for the Air Max shoes up is the demand by consumers. Thanks to the influence of technology, comfort, design, style, and hype, many sneakerheads cop Air Max sneakers, and thus, due to demand and supply chain, the sneakers are more expensive.

The general consensus is that they fit true to size, but if you've copped a size up, you can always add an insole to make them fit like a glove.

Locate the tag inside your shoe. All authentic Nike shoes have a tag sewn into them with their size, barcode and model number on it. You will recognize it most easily by the barcode.

The Air Max 270 fits true to size. Those with wider feet may opt to go a half size up for a roomier fit, while those with narrow feet may opt to go a half size down for a snugger fit. It is worth noting that the elevated midsole gives the shoe a unique fit that may take some time to get used to.
