The adidas ZX 2K Boost ‘Solar Yellow Red’ showcases an eye-catching color-fade effect on the sock-like upper, built with a lightweight blend of mesh, synthetic suede, and TPU. The gradient effect features bold red on the forefoot transitioning to a neon green finish on the heel, complemented by contrasting black accents on the three-stripes and molded heel tab. The Hi-Res Red hue on top is mirrored on the Boost midsole, enhanced with a semi-translucent cage that wraps around the heel.
