adidas Gives Its UltraBoost 21 a “Halo Silver” Makeover

To jumpstart 2021, adidas is giving its updated UltraBoost 21 silhouette a NASA-approved “Halo Silver” makeover dressed in a tone-on-tone grayscale arrangement of “Halo Silver” and “Grey Two.” Darker grey dresses the upper, Three Stripe lace cage and heel clip, while a lighter tone covers the midsole, branding, and laces.

In terms of technical specs, the upcoming adidas UltraBoost 21 “Halo Silver” is crafted with a signature Primeknit upper — which includes at least 50% recycled Parley Ocean plastic — while the Boost-assisted midsole includes 6% more foam. Additionally, the adidas LEP (Linear Energy Push) technology and restricted Continental rubber outsoles add a performance-driven upgrade to the silhouette.

The adidas UltraBoost 21 “Halo Silver” is scheduled to release on February 4 at select retailers and adidass.com for $180.
