Just 2 months after receiving the sneakers and after limited use (as seen in the photos) both developed holes in the thumb area. The back of the right one also cracked, revealing what appeared to be a plastic tip (see the green circle in the last photo). It hurts me and makes the shoe completely unusable. I've never had to throw away my running shoes so early. Really bad quality. I've been a regular Nike customer ever since. Extremely disappointed.
