Nike Men’s Shox NZ running shoes, Men size 11 US Premium Leather and Synthetic upper Shox provides cushioning and impact protection These shoes have been worn one time, when I tried them on and walked around the store. I would still consider them brand new, due to no flaws in each shoe. If I failed to cover anything about the shoe, please let me know and with my minimal knowledge of shoes, I’ll try to answer your questions as best I can.
