One shoe was defective, one  of the rises at the back of the heel was missing/malformed. I had initially thought it was folded inward and could be fixed, but was mistaken. By the time I realized that there was no way of fixing them, it was too late to return them. I paid 46 dollars for unusable  shoes that should never have survived a minimally competent Quality Control inspection, which neither the manufacturer nor vendor appears to have conducted.
