I saw these on an auction website and really liked them, but they were the wrong size and there was no other info about them. Does anyone know what specific model these would be so I can search for them? In the pic it says Nike Running, but that isn't much help. I've tried searching for "blue nike running shoe gray swoosh" but no luck. I've found others that are similar, but I just don't like them as well. I really want to buy a pair, but if I can't find them... I also tried perusing Nike's website, but searching for a specific shoe seems to be like searching for a needle in a haystack. I've attached a screen shot I took from the auction site, but the auction is long over and I can't find the page anymore.
