Launching as part of the ‘Geometric Pack,’ the adidas UltraBoost 20 ‘Core Black Grey’ combines a tonal all-over print with a sustainable build, highlighted by breathable Primeknit construction that weaves in recycled Parley Ocean Plastic. The geometric design up top makes a repeat appearance on the full-length Boost midsole, reinforced underfoot by a grippy Continental rubber outsole with adidas’ stabilizing Torsion technology. Size 11 Great condition! Please see photos for minimal wear.
