1. DATE CODE: Most, not all, Nike retail boxes feature a date code stamped inside the box.
2. HEEL TAB: Air Presto Flyknits have a woven pull tab on the heel. Note how this pull tab sits very round and open due to the nature of the rigid plastic.
3. PRESTO LOGO: There is a Presto logo debossed into the lace cage plastic. The edges of the letters should be slightly rounded but well defined. Look for the tiny Swoosh between the E and S.
4. AIR LOGO: On the heel of the outsole is an Air logo embossed into the rubber. Make sure the typeface used is correct and that the letters should have sharp edges.
