2nd pair of Solomon soles pull apart after 3 weeks

This is the second pair of Solomon tekkies I buy and after 3 or 4 weeks the soles pull apart from the shoe. If you pay almost R2000.00 for a pair of shoes you would think it would last a while longer. And I am not the only person, two of my friend's Solomon's are doing the same after a few weeks. It is such a disappointment. It is actually pathetic. What a waste a money, should have taken the Adidas.
