The adidas UltraBoost 22 ‘Legacy Purple’ delivers a monochrome rendition of the performance running shoe. A subdued violet hue suffuses the breathable Primeknit upper, composed of 50% recycled Parley Ocean Plastic and 50% recycled polyester. The one-note palette is disrupted by ‘UltraBoost’ embossed on the TPU heel counter in bright red lettering. Responsive cushioning arrives via a full-length Boost midsole coated in a 3M reflective finish. Underfoot, the Stretchweb outsole features Continental Better Rubber for optimal grip.
