RTFKT (Artifact), the virtual fashion brand that gained significant attention after being acquired by Nike in 2021, unfortunately, ceased operations within Nike at the end of January 2025. However, the Dunk Genesis collection, which was announced in 2022 and expanded from virtual to physical products, continues to maintain high popularity.

Due to the limited distribution and high rarity of this series, buyers must exercise caution when purchasing from secondary markets, as many counterfeit versions exist.

This article focuses on the RTFKT x Nike Dunk Genesis “Void Edition” and examines how professional authenticators at SNKRDUNK determine whether items are authentic or fake. While the information presented here represents only a portion of authentication methods, it serves as a valuable reference for those hesitant about purchasing items from secondary markets.

About the RTFKT x Nike Dunk Genesis “Void Edition”

The Dunk Genesis collection was announced in April 2022 by RTFKT, the virtual brand acquired by Nike in 2021. The collection initially launched as a forging event through NFTs, with token holders gaining access to physical pairs through a unique approach that generated significant buzz. In Japan, the collection was exclusively available through DSMG, resulting in limited distribution quantities.

Authentication Point

▪︎Box

The first authentication point involves examining the box packaging. The color tone of the logo on the plastic components differs between authentic and counterfeit versions. Compared to authentic pairs, counterfeit versions display a stronger green coloration in the logo.

▪︎Midsole

The midsole features “Air ZOOM” text printed in matching color on authentic pairs. However, counterfeit versions lack this printing entirely.

▪︎Upper (UV Reaction)

When examining the upper’s UV reaction, authentic pairs show a faint green-like reaction in the grid pattern areas under ultraviolet light. Counterfeit versions react with an orange color and display characteristic dotted lines that become visible under UV inspection.

▪︎Insole

The insole surface treatment differs significantly between authentic and counterfeit pairs. Authentic versions feature textured embossing, while counterfeit versions lack this treatment and instead display printed black patterns on a smooth surface.

▪︎X-ray Analysis

X-ray examination reveals internal markings that distinguish authentic from counterfeit pairs. Counterfeit versions show internal engravings that include Chinese characters, which are not present in authentic pairs.

▪︎IR Camera

Finally, infrared camera analysis provides another authentication method. Under infrared inspection, authentic pairs show shoelaces and stitching that appear white, while counterfeit versions display these elements in black.

Conclusion

The authentication points discussed in this guide represent only a portion of the comprehensive authentication process. SNKRDUNK conducts thorough authentication by examining multiple additional factors before making final authenticity determinations. As counterfeit manufacturing techniques continue to improve daily, identifying fake products through amateur methods has become extremely difficult for non-experts.

Professional authentication services that provide highly accurate authenticity verification by expert authenticators are recommended for secure purchases.

The combination of advanced authentication techniques, including UV reaction testing, X-ray analysis, and infrared camera examination, demonstrates the sophisticated methods required to distinguish between authentic and counterfeit pairs in today’s marketplace.
