Noticed too late - a real bad buy

Have this shoe bought in July 2013 for 40.77 - a K-Swiss bargain I thought ...
However, I realized after a few weeks - this shoe, it was not - it had only a few times since worn a bit uncomfortable and now the heel is towards even frayed.
Pity of the optics but so promising.
Unfortunately, only 1 * because they have kept only 3-4 months ...
