Adidas has brought back the old ZX 500, but in a new and innovative form - ZX 500 RM. In the 80's runners were all over the ZX-runners with a high technology design based on biomechanical research. These streetwear shoes have been reinterpreted with a modern design that fits today's look and technology. They combine an upper in mesh and suede with their modern cushioning BOOST system to give it a light and energetic feeling.
