UltraBoost 21 'Grey'
The adidas UltraBoost 21 ‘Grey’ applies a monochromatic neutral finish to the lightweight and responsive performance running shoe. The sneaker’s breathable knit build, incorporating recycled Primeblue materials that include Parley Ocean Plastic, sits atop full-length Boost cushioning that packs 6% more Boost capsules than the UltraBoost 20. Underfoot, a revised Torsion system dubbed Linear Energy Push yields improved forefoot stiffness and energy return.
