The Feature x Shadow 6000 'Living Fossil' was released in June 2018 as a collaborative project between Saucony and Las Vegas' Feature Sneaker Boutique, drawing inspiration from Nevada's state fossil, the Ichthyosaur. This stylish retro runner features a suede and nubuck upper in a captivating Shonisaurus Grey color, boasting a water-resistant toebox. The design is accentuated with vibrant holographic elements, notably on the heel and Saucony logo's signature dots, providing a pop of bright green. The midsole showcases a unique speckled pattern with a gradient effect transitioning from black to green. This remarkable collaboration effortlessly combines classic aesthetics with a contemporary twist, making it a sought-after sneaker amongst enthusiasts.
