DerrickTranThanks for bringing this to my attention. Generally speaking, I don't rerun a product until 100% of the previous orders have been delivered, but I didn't catch it this time. Fortunately, the remaining pairs from the last drop (10 2-packs that were delayed from a shipping error) are being shipped to our fulfillment center right now. You should have tracking info by the end of the week. My apologies for the delay and the confusion.
