Due to the current panic and the backlogs that it has created this upper is available for backorder but will not ship until May/June. When you place the item on backorder the system will check your card to make sure the funds are available but will not capture them. Once the upper is ready for shipment we will contact you for updated payment information. Once you place the backorder do not call and ask for the status as this just slows down the completion of your order.
