This is a brand new pair of ASICS Gel Quantum 360 5 knit shoes in a size 12 men's. The color is tuna blue and midnight. The upper, I think, is a synthetic mesh type. These shoes have never been worn, only tried on.  If there are any questions please feel free to ask. I only ship to the lower 48 states so continental US bidders only. Pay within 3 days of auction end, thanks. Sorry for the high shipping prices but USPS recently went up on their prices again forcing me to go up on mine.
