Before buying used sneakers, establish three separate things: whether the size and shape suit you, what condition the actual pair is in, and whether you have enough evidence for any authenticity claim. A clean upper or a photograph of a box cannot answer all three.
This guide is a condition-and-fit checklist. It cannot authenticate shoes, certify their safety or estimate how many kilometres of cushioning remain.
Decide what you need the shoes for
An everyday outfit purchase and shoes intended for regular running are different decisions. If you need reliable performance for training, photographs alone cannot establish the history or condition of internal cushioning. An attractive price does not remove that uncertainty.
Ask how the pair was used and whether any parts were replaced or repaired. Treat the answer as seller-reported information, not a verified mileage record. Nike's running-shoe guidance explains that midsole cushioning can deteriorate even while the outsole appears intact. That running-shoe guidance does not provide a photo-based remaining-life test for a particular pair. Be cautious about a performance claim supported only by “barely worn.”
Request this photo set for both shoes
| View | Look or ask for | What it cannot establish |
|---|---|---|
| Both outsoles, photographed straight on | Uneven wear, worn areas, visible damage | Remaining cushioning or an exact usage history |
| Both heels from behind | Differences between shoes, heel lining wear | Whether the shoe will feel stable on your foot |
| Inner and outer sides | Visible splits, separation, repairs | Strength of every bond or hidden material condition |
| Toe areas and upper | Tears, worn fabric, marks and creasing | Whether a mark can be removed |
| Interior and insoles where accessible | Lining wear, missing or replaced insoles | Hygiene or comfort from a photograph |
| Complete size labels | Brand/model information and sizing system | Fit or authenticity by itself |
Ask for a close-up of any questionable area and a wider photograph showing where it is. Do not request destructive flexing or attempts to peel a sole apart. If a fault needs a specialist's judgment, get that judgment or pass.
Read the size label carefully
Check whether the listed size is UK, US, EU or another system, and whether the chart is for the relevant product range. Do not assume “size 8” means the same thing in every listing.
Nike's South African men's footwear chart specifically distinguishes foot length from the CM value on its labels and recommends measuring both feet. Use the appropriate manufacturer's model/range guidance; this is not a universal conversion table for every sneaker.
If you have worn the same model before, that is useful personal context, but a pre-owned pair may still feel different. An insole measurement is another piece of information—not a substitute for every aspect of fit.
Keep condition and authenticity separate
Good-condition photographs do not prove a branded pair is authentic. Equally, an authentic pair can be heavily worn. If the purchase depends on authenticity, ask what evidence supports the claim and understand the scope and limits of any verification service before paying. This checklist is not such a service.
Avoid treating a receipt, serial-style code, packaging or a single visual detail as conclusive on its own. Do not label a seller's item counterfeit simply because one photograph is unclear.
Use a stop-or-ask decision
Ask for more evidence when the two shoes are not both shown, a size system is missing, or a visible repair is unexplained. Pass when the intended use requires reassurance the available evidence cannot provide, or when the total cost only makes sense if an unverified restoration succeeds.
Suggested message—not a customer quote:
Hi! Could you add straight-on photos of both soles, both heels, the inner lining and complete size labels? Please also mention any repairs or replaced insoles. I'm considering these for everyday wear and want to understand the actual condition before buying.
Add the delivered total and any necessary care or repair estimate to your buying budget. A low listing price is only one part of the decision.
