What the record says
Sizing on Dior B30 B31 Sneakers is the first place a Footwear entry goes wrong, and the easiest to settle early.
Weight for this entry falls in the 700–1,100 g band, estimated from the Footwear category and not measured on a bench. Sizing sits at EU 36–45. On the bench, the tape follows insole length, outsole width and stack height. Recorded for this entry: the listing traces to Weidian item 7623763389 and carries this record's own reference 1811775800.
Everything else is secondary to these three points. First, sole glue line along the midsole — the point that separates two batches most reliably, and the cheapest one to re-shoot. Second, size tag inside the heel vs the ordered EU size, held against the requested size, which is the figure that decides a return. Third, stitching density at the toe box, photographed at an angle shallow enough to reveal uneven edges instead of hiding them. Each point is captured before the parcel is closed, and a failure at any one of them holds the entry back for a second reading.
Freight behaves predictably here: the original shoebox decides the volumetric side of the freight calculation far more than the foam does. The bench sequence is one shoe, then both together, then the carton. Two pairs from the same entry consolidate cleanly into one carton; a third usually pushes the parcel into the next freight band. Heel counter stiffness is the single best proxy for whether a pair will keep its shape after a fortnight of wear.
Nothing here is stable between runs. Lasting, adhesive cure and leather or knit batch all move between production runs, so two pairs of the same entry rarely read identically. The three points above are kept precisely because they stay readable across that drift.
