After being an Ebay member for 20 years, you can feel reassured that there is no guessing when you purchase from my store. All of the items in my store are Authentic (new and pre-owned) and are either purchased online/in person at reputable stores in the US. I just recently started downsizing my own collection of Nike shoes (new and preowned) and have listed them as well. All items are in a smoke free location. Thank you for looking and I truly appreciate your positive feedback after your purchase. (a lot of my buyers do forget to leave feedback-which is important for us sellers on Ebay)
