The UltraBoost 2020 Black Gold? makes use of a monochromatic design, supported by 20% more Boost cushioning compared to the original UltraBoost. The upper utilizes a breathable Primeknit build that hugs the foot with lightweight support. A lone pop of contrasting color appears on the metallic gold 3D heel frame, overlaid atop a soft elastane heel for added stability. Underfoot, a grippy Continental rubber outsole maintains the all-black aesthetic.
