The company itself looked at the photo sent and said it was damaged during shipping.Oh yea, that's definitely the belly part of leather. It's like that because it's not stretched over the back muscle of an animal but instead hangs across & under the belly area and there's also a lot more fat under it.
In turn, this leather is thinner, stretchier and slightly weaker but it's still more than usable for clothes, just perhaps not as much for footwear.
Regardless, I don't really see this happening on Cyber Lips boots. It could be close to the belly but it's still, well, good.
Either way, it's one million percent not damage and people claiming it's damage should get sent to jail.
