Pre-Owned Nike Invincible 3 Running Shoes - Size 9.5 Men / Oatmeal, Navy, Orange. Max cushion running shoe. Nike's ZoomX foam is ultra plush, bouncy, comfy, and comfortable for running and walking. As you can see from the pictures, these have significant scuffs and wear from previous use, but are still a tough, structurally sound and durable shoe. I always wash my shoes before selling and when I was scrubbing the soles some of the orange and blue paint brushed off. The lightweight mesh material the shoes are made from is very strong and there are no rips or tears in the shoe's upper.
