Made in collaboration with Sega, the RS-X3 'High Risk Red' pays tribute to the gaming brand’s Sonic the Hedgehog franchise. Unique details include the titular character’s silhouette, etched on the heel tab above a trio of gold rings. Matching metallic gold is used on the tongue tag and high-score text printed on the sculpted foam midsole. Up top, a translucent overlay covers the textile upper, revealing a gradient black and red finish.
