The path to the future is built on the lessons of the past. With that in mind, these adidas ZX 700 HD shoes revisit their roots as the high-mileage running shoes of the 1980s. Comfort and casual style are stronger than ever. Now that they've been updated with recycled materials, you've got - dare we say it - perfection? Put them on and see what you think. This product is made from recycled materials as part of our ambition to end plastic waste. 20% of the parts used to make the upper are made from a minimum of 50% recycled materials.
