The women’s UltraBoost 20 'Tech Purple' features split color blocking on the upper, constructed from breathable Primeknit with soft elastane at the heel panel. Metallic silver three-stripes complement a matching 3D heel frame, good for a locked-in feel at the back of the foot, while Tailored Fiber Placement offers stitched-in reinforcement at the sneaker’s forefoot. It all rides on a full-length Boost midsole, supported underfoot by a Continental rubber outsole.
