The adidas Yeezy 450 ‘Stone Flax’ dresses the futuristic silhouette in a neutral monochrome finish that falls in line with the traditional Yeezy aesthetic. The dual-layer Primeknit upper features a stretchy sock-like cuff with traditional lace closure. Structural support is provided by tapered polyurethane ‘fingers’ that extend up the sides, bringing a visual dynamism to the minimalist build. The lightweight polyurethane midsole is reinforced underfoot by a wavy-traction rubber outsole.
