I have the same pair of shoes which I purchased last year. I have only been wearing them for about 6 months (less wear on the soles than in your pictures) and the same problem has happened to me, split where the toes bend. I would have never noticed except for the fact water soaked through the bottom when I stepped in a puddle the other day. I emailed their customer support and I have not heard back from them. The shoes are very comfortable but this problem is very disappointing.
