Purchased shoes with spenco since the salesperson mentioned the unconditional guarantee as long as I kept the box. Returned today with the box in hand well within the year. The top layer of the inserts were falling apart. Nonetheless, the salesperson refused an exchange because his system does not go beyond 30 days. The barcodes were clearly visible and the same as the new ones they offer, so much for the unconditional guarantee and chalk one up for the sales tactic. I won't support a company that doesn't abide by their own promises.
