Turn the shoe over first. Not because the sole is the prettiest part of a sneaker, but because it is the part that fails in a way you cannot live with. An upper with a slightly wrong shade of swoosh is a shoe you wear anyway. A midsole that separates at the toe in month three is a shoe in a bin.
The sole is also where a factory's shortcuts are structural rather than cosmetic — moulds, foam density, adhesive, and cure time — and none of those are things a seller advertises or a warehouse photographer thinks to shoot. So this check is mostly a matter of asking for the photographs nobody sent you.
Work bottom-up
The outsole tread. Compare the pattern against a reference image of the retail pair, at the same angle, whole-foot. You are looking at the geometry of the moulding: are the lugs the same shape, do the flex grooves land in the same places, is the rubber the same colour of translucent. This is a mould comparison, and a mould is a fixed cost the factory either paid or did not.
The bite of the tread. Depth and sharpness of edges. A shallow, soft-edged tread is a worn mould or a rushed cure and it wears smooth quickly.
The midsole sidewall. Then the paint. Sidewall paint on a replica is often sprayed rather than moulded in, and sprayed paint on flexible foam is the single most common source of wear complaints. One buyer, describing a pair a month in:
The paint on the tip of the shoe scratches off easily, but i dont really mind. They get dirty very fast, cus its a white shoe and its pretty hard to clean them.

Note the shape of that comment. It is not a rejection — they kept the shoes and rated them. Cosmetic paint wear is something people decide they can accept, and the useful thing is deciding it before the shipping bill rather than afterwards.
The glue line. Where the upper meets the midsole, all the way around both shoes. You want a consistent gap and no squeeze-out. Yellowed adhesive, a bead of glue on the upper, or a line that is thick at the heel and invisible at the toe are the three shapes this fault takes. Ask for a photo along the seam, at eye level with the table, not from above.
The heel counter and the stack. Look at the shoe in profile against a reference. The height of the stack, the angle of the heel, and where the midsole steps up are shape decisions cut into the mould. If the profile is wrong, everything else about the pair is a detail.
The insole. Lift it if the photo allows. Print, branding and the foam underneath are all worth a shot — the underside of an insole is a common place for a factory to skip a printing step entirely, and the interior parts nobody photographs go further into that.
The pair is its own control
Two shoes came out of the same factory, on the same day, and are being photographed on the same table under the same lights. That makes the left-versus-right comparison the most reliable check you have, because it removes every excuse a seller can offer about lighting or camera or angle.
Set them sole to sole in one frame and look for differences in paint coverage, glue line, tread colour, and how the two heels sit. Differences between the pair are unambiguous. Differences from a reference photo taken in a studio five years ago are arguable.
Ask for that specific shot if it is not in the set — both shoes, soles together, one image.
What a swap fixes, and what it does not
This is the part that costs people weeks. A defect on one unit gets fixed by a replacement. A defect in how the run was made does not, and the record contains a clean example of somebody learning it:
I ordered a pair from sixgods using allchinabuy and had it exchange because the print on the heel is too low. The exchange pair has arrived but the issue is still the same.

The full thread is on the SIXGODS evidence page. Read it as a mechanism rather than a verdict about that seller: a placement fault came from the pattern, so the second pair had it too.
The same logic runs the other way when a seller tells you a known flaw has been fixed:
Many other sellers have claimed the latest AP batch has resolved the shoe cracking issue but various other posts have cropped up none of which shows the issue has been resolved and new flaws around logo not being centered etc have been pointed.

A "fixed" batch is a claim about a production run, made by the person selling it. What a batch is explains why the run, not the seller, is the unit that owns a flaw, and the batch notes list the known per-run problems on the silhouettes they cover. When the fault is in the run, the fix is a different batch.
What our record does not contain
This site holds 237 quoted Reddit comments about 124 sellers. Not one of them uses the words sole, midsole, outsole or insole. The sneaker comments we hold are about print placement, paint, comfort and fit — not construction.
So nothing here supports a claim about which sellers or which runs have sound sole units. What it does support is the observation that the sneaker complaints in the corpus cluster in exactly two places: something printed in the wrong spot, and something that came off. Both are visible in a photograph if somebody takes the right one.
Before the sole, and after
Get the size question settled first — rep shoe sizing does not track the number printed on the box, and no amount of sole inspection saves a pair that does not fit. Then work the upper: logos, fonts and spacing is where sneaker flaws are most often visible, and any stitched panel gets the stitching checks.
