FAKE

Examine suede texture and burgundy hue consistency under natural light; authentic pairs display even nap, saturated color without blotches, and symmetrical panel shapes. Check stitch alignment across overlays and tongue, ensuring double-stitching is uniform. Inspect midsole color, outsole pattern, and Nike Swoosh proportions. Authentic models avoid glue stains, mismatched dyes, or uneven embossing in visible areas with consistent toe box.

Verify tongue and insole labels for correct FN0619-600 style code, precise font, and correct country coding. Size tag inside shows consistent spacing, accurate UPC, and manufacturing dates matching known release windows. Authentic labels use clear printing, aligned stitches bordering tags, and a smooth backing. Blurry fonts, missing hyphens, or misaligned serials indicate counterfeit craftsmanship; check QR codes for legitimacy verification.

FAKE

Inspect suede quality and light bone tone uniformity; authentic examples show smooth suede grain, subtle tonal transitions, and precise panel curves. Look for neat edge painting, consistent perforation holes, and evenly applied overlays. Check heel tab symmetry and tongue foam silhouette. Counterfeits often show color bleeding, irregular stitching, or uneven suede nap that reacts differently when brushed under varying light.

Confirm the internal size tag lists FZ5654-100 style code and a matching UPC; fonts must be crisp with consistent letterweight. Inspect country of manufacture, manufacturing week, and alignment within tag borders. Verify tongue tag stitching is flush and not puckered. Authentic labels resist smudging, maintain barcode clarity, and include accurate hyphens and serial sequences that match release data in databases.

Assess leather panels for smooth, pebble texture and consistent white-to-umber shading; authentic materials display uniform dye absorption and tight, even stitching. Check lace quality, eyelet alignment, and tongue shape for symmetry. Inspect outsole tread for correct pattern depth and color. Any sloppy glue marks, mismatched panels, or inconsistent perforations suggest non-authentic production standards; confirm heel counters feel solidly reinforced always.

Examine the insole and tongue labels for HJ5870-100 style identification, crisp print, and matching UPC barcode. Verify size tag includes accurate EU, US, and CM conversions and a production week consistent with release. Label edges should be smoothly integrated with stitching lines. Faded ink, smudged barcodes, or incorrect size matrices are reliable indicators of counterfeit labels; check serials online carefully.

Review synthetic leather grain and fabric panels for uniform texture and true white color; vintage treatments should appear intentional and evenly applied.

Confirm style code BQ6806-100 appears on the internal tag with matching box label; font weight, spacing, and hyphen placement must align with verified examples. Inspect manufacturing country and week, and ensure barcode scans correctly. Tag stitching should be flat and even. Misprinted codes, incorrect country abbreviations, or crooked tag placement are common counterfeit signs to avoid; cross-check with POIZON records.

Use high-resolution photos, compare stitching patterns, check sole texture, and inspect insole printing closely. Sizes, weight, and material feel often reveal inconsistencies. Keep receipts and original packaging. When in doubt, rely on POIZON's authenticated listings and request additional images. Authentic pairs show consistent color bleeding, precise logo placement, and uniform adhesives without excess residue or mismatched materials under light magnification.
