If you’re clocking serious mileage and want a pair that hits hard on both performance and style, the Adistar “Core Black” from Stella McCartney and adidas has you covered. It offers comfort and sustainability without compromising on looks—perfect for runners who care about their stride and their impact.
The REPETITOR midsole uses two foam densities: firm at the heel for support, and softer under the forefoot for added bounce. This setup keeps your legs fresher on longer runs. The rocker shape in the sole helps roll your foot forward with each step, making transitions feel smooth and natural. Underfoot, the Adiwear rubber outsole grips to a variety of surfaces—think city pavements, damp roads, and park trails—and holds up even with regular wear.
adidas built the upper with Primeknit, so you get a snug, breathable fit that flexes with your movement. It keeps your feet cool and avoids hot spots. TPU overlays at the sides and a reinforced heel lock your foot in for extra stability, especially useful during longer sessions. Stella McCartney brings the ethics too—no leather here. adidas made the entire upper using 100% recycled polyester and kept the whole shoe vegan-friendly.
Even though the Adistar looks chunky, it doesn’t feel heavy. The cushioning stays consistent, even deep into your runs. One runner called it “built like a tank”—but meant it in the best way. Others praised how the rocker design naturally pushes them forward, reducing strain late in the session.
