I have a size 9.5 (fits like a 10 though) pair of Mizuno Wave Universe 2 racing flats for sale for dirt cheap.

They're mega-light at 3.9 oz. And in the color shown in the link above. They've only been used in two 5ks. Great flat, just too light for me.
Does anyone want them for cheap? Make a reasonable offer and they're yours.
