Tired to purchase these for my son for Christmas, didn't receive them until 20 days later, well past Christmas. He loved them, until the right shoe ran out of battery (10 minutes after he opened the package) and tried to charge them. The right shoe's USB port did not fit well with the charging cable, so we never could get it to light up again. Sent some more emails to customer service and finally came to the conclusion that these need to be returned. YOU MUST PROVIDE PICTURES, PAY A 15% RESTOCKING FEE, AND PAY FOR FREIGHT! These shoes cost me way more than they're worth, considering I have nothing to show for it. Now I'm waiting for my return label, it's been 30 minutes and no email yet. Guess I'll wait around all day, I have nothing else to do, right?
