The sneaker's upper is constructed of a prime knit material with a more specific knit construction for added performance and support. It also incorporates pink color scheme, while a recycled Parley Ocean Plastic material shades in its outsole design. White color dominates the upper with accents of Lime Green on part of the vamp section, heel stabilizer and inner lining, while Solar Yellow makes its way on the outsole, and black on the Three Stripe branding on the quarter panels and toe cap. Underfoot, the thick boost midsole incorporates a torsion system, and a rubber outsole graces the shoe.
Our experts think the unique feature of this shoe is its torsion system, which consists of Light Energy Push for a more reactive performance. The adidas Ultra Boost 21 White Solar Yellow debuted on February 4th, 2020, and retailed at $180.
