From the playground to the sidewalks, the Nike Crater Impact makes a statement. The feel-good design is made with at least 20% recycled content. They feature Crater foam cushioning, so you can make an impact while you play in more ways than one. Crater foam cushioning uses about 11% Nike Grind to give it a space-age look. It feels lightweight and bouncy under your heels and toes. Fabric made with recycled fibers is designed to feel lightweight and durable, and an overlay at your midfoot helps with stability while you move. Rubber on the sole uses about 15% Nike Grind made with rubber scraps from the footwear manufacturing process.
