To commemorate the five-year milestone of the iconic Adidas UltraBoost, the UltraBoost 20 '5th Anniversary Pack' has been introduced. This exclusive edition features a sleek black Primeknit upper that snugly embraces the foot, delivering a comfortable sock-like fit. The upper is also reinforced with contrasting purple threads through the Tailored Fiber Placement technique. Adding a touch of elegance, the silver three-stripes are accompanied by a gradient finish elastane heel in shades of grey and white. Furthermore, the Boost midsole is treated with a gradient coloring that gracefully transitions from purple to black to white. This distinctive design element adds a visually striking and dynamic appeal to the shoe.
