A practical comparison order
Put both pages side by side. Compare product identifiers, colour naming, option count, visible materials, logo placement, sole or seam shape, size charts and measurement units. If the photographs differ, look for crop differences before assuming they show separate batches.
Know when to stop
Do not infer seller identity, batch, quality or authenticity from a title. If a decisive field is missing, treat the match as incomplete and ask for the missing image or measurement.
