Notes： Dear Valued Customer, Please be advised that because the heated Socks have built-in batteries, they must be shipped using special logistics methods. If your order status shows "delivered" but you have not received the parcel, it may have been placed at a designated pickup location nearby, or the carrier may have attempted delivery unsuccessfully and will try again. Please check your surroundings and any notification left by the carrier. Should you have any questions, please contact our customer service team via the store first. We are always here to assist you. Thank you for your understanding.
