For sneakers, you may cancel your order within 3 hours of placing it or before it is confirmed by the seller - whichever comes first. If 3 hours have passed from when you placed the order and/or the seller has already confirmed the order, then the order cannot be canceled. If neither have occurred, you can cancel your order first by accessing it via “Track My Order” or “My Account,” clicking “Cancel Order” and following the instructions.
If you checked out as a guest, you will need to create a Flight Club account.
