The Edge XT ‘Core Black’ utilizes a monochromatic stealthy finish on a breathable textile upper, reinforced with TPU overlays and a molded external heel counter for added stability. The blacked-out coloring up top is countered by a Bounce Lite midsole in a crisp white finish. Underfoot, a durable black rubber outsole is fitted with an X-shaped adidas Torsion bar, good for midfoot support and a springy feel.
