adidas celebrates the UltraBOOST silhouette and its five year anniversary with a blend of classic colours. The sock-like PrimeKnit™ upper features a woven indigo threat around the toe box and behind the reflective 3-Stripes overlay. A moulded heel counter panel features an ombre appearance and is overlaid with moulded Fitcounter windows. The full length BOOST™ midsole is wrapped with a flexible Stretchweb outsole with Continental™ Rubber outsole. A visible Torsion® System stability support and moulded plastic lacing cage complete the silhouette.
