I've been buying these shoes for about a year because they are quite durable for a man with flat feet and last 3-4 months before I feel like the sole is breaking. But now they come with an ecology lecture (an old shoe on the left, a new one on the right). Honestly it's pretty stupid and I'll look for another brand when they wear out. Just create your product. If you want, do it responsibly and without harming the environment - I'm all for it. Just don't preach on the product.
