So I have 3 pairs of barricade 6.0 and one of the outsoles is about to wear out at the toes. I think I have another month left. I bought them all within 2 months of each other and less then 6 months ago, but I can currently only find 2 receipts. One was a paypal invoice from the * B A Y and another from an authorized retailer. The receipt from the retailer states a different color in abbreviation "BKBKR" then the one that wearing out. If I send in the shoes with either of these, you think I can get a replacement? Also, is it me or did adidas raise their return fee for shoes?
