The adidas ZX 2K Boost 'Solar Yellow Red' sneaker boasts a visually striking color-fade effect on its sock-like upper, which is constructed using a mix of lightweight materials including mesh, synthetic suede, and TPU. The gradient transition begins with a vibrant red on the forefoot and smoothly shifts to a vibrant neon green on the heel. Additional contrasting elements include black accents on the three-stripes and molded heel tab. The Boost midsole not only showcases the same eye-catching Hi-Res Red hue but is also equipped with a semi-translucent cage that provides extra support and wraps around the heel for added durability and stability.
