How to identify Nike sneakers
Quick answer
Identify Nike sneakers by the style code on the product tag or box, a code in the format xxxxxx-xxx. Match the full style code, size and condition before comparing prices; a silhouette name such as Air Force 1 covers many different colourways and releases.

Read these identifiers
- Find the size label inside the shoe, usually behind the tongue, and photograph it. Nike lists the style code, in the format xxxxxx-xxx, on the product tag and on the shoe box.
- Search the full style code. The part after the dash identifies the colourway, so a code without it matches the wrong colours.
- Record the size in the system printed on the label (US, UK, EU or cm), whether it is men's, women's or kids' sizing, and the manufacture date Nike prints on the product tag.
Check condition before you buy
- Check the outsole and heel for wear, the midsole for creasing, yellowing or crumbling, and the insole and lining for tears.
- Foam and glue in older pairs can break down even when the shoes were never worn. Flex the sole gently and look for cracks or separation before buying.
- Note whether the original box, lid and spare laces are present, and whether the box label matches the label inside the shoe.
Avoid these comparison mistakes
- A matching style code on the box does not prove the shoes inside are that pair; compare the label inside each shoe.
- Worn, clean pre-owned, unworn and box-damaged pairs sell differently, so keep them in separate comparisons.
- This guide does not authenticate shoes. For doubtful pairs, rely on the seller's evidence and a professional authentication service.
Compare the same item, not just a similar name
Search the full style code with the size, then filter by condition and whether the original box is included. Sizes at either end of the range can sell differently from common sizes, so compare the same size where the evidence allows. Scan the size label to start identification, then confirm the style code yourself.
