UltraBoost 21 'Black Active Teal'
The adidas UltraBoost 21 ‘Black Active Teal’ adds subtle pops of color to a holistic running shoe that blends lightweight support, responsiveness and comfort. The upper is constructed from breathable Primeknit, made in part with recycled materials that include Parley Ocean Plastic. The monotone finish up top is disrupted by a teal-colored heel counter and fuchsia adidas branding on the tongue. The same contrasting hues enliven the full-length Boost midsole and Continental rubber outsole.
