The Raf Simons Cyloon-21 in bold monochromatic red is a avant-garde streetwear sneaker featuring a sculptural, multi-layered midsole with integrated transparent TPU windows revealing internal cushioning elements. The upper combines perforated suede and smooth leather panels, accented by a distinctive white plastic clip with embedded red resin at the heel counter—a signature architectural detail of the Cyloon line. 'RAF SIMONS' branding is debossed on the side midsole flanks, reinforcing designer identity. The shoe sits atop a chunky, ridged rubber outsole for visual impact and stable traction. Engineered for fashion-forward wear rather than athletic performance, it offers moderate comfort via foam cushioning but prioritizes aesthetic statement over technical function. Ideal for urban street style, gallery visits, or high-concept casual outings where bold silhouette and designer credibility matter most. The all-red execution creates a cohesive, immersive look, while the translucent accents add depth and modern tech-inspired flair. Size EU 40 as indicated on box label (HR740007S, 0047).
