We could use a lot of superlatives to describe the Nike Air Max 2021.We could tell you that we've incorporated recycled materials to design a sneaker with at least 20% recycled content.Or that the new Air cushioning unit underfoot is our most revolutionary.Perhaps we'd call it the the pinnacle of comfort; waxing poetic about the cored-out foam midsole that gives you the lightest. softest feel.But maybe we just say it's modern meets technical with a splash of heritage DNA.What fun is there in giving away the surprises?
