adidas introduces the UltraBoost Mid Prototype, uncovering a range of unreleased silhouettes from their archives. Acting as a predecessor to the UltraBoost Mid, this shoe showcases a striking Solar Yellow Primeknit build on a mid-top structure. Enhancing its aesthetic, the design incorporates a ribbed collar in High Res Blue, along with white Three-Stripes branding and mismatched navy/grey overlays. Furthermore, the shoe guarantees stability through an external heel counter, while the full-length Boost midsole ensures exceptional cushioning for the wearer's ultimate comfort.
