CAUTION!! TO AVOID CAUTION!!! Authentication process does not exist. Of the last three purchases, two were contested. A pair of fake and reimbursed Yeezy Sesame after endless exchanges of emails with the support ... I have restored confidence in StockX and I have purchased other Yeezy desert sages that have obvious defects such as orange stitching on the center of the upper, which are not eligible for sale because only for the defects they present (if they were not fake) CANNOT pass the Adidas quality control nor the StockX authentication control (which obviously does not exist) For these shoes I still have a dispute that will turn into a PayPal complaint from day 04/20 Furthermore, when you reply to their justifications, customer service responds arrogantly and with threatening tones. TO AVOID DO NOT RISK YOUR MONEY AND YOUR TIME.
