A friend of mine who works for Mizuno sent me a pair of Wave Spacers in a size 12.5 to try out. He swore I would need a half size large, but they are too big (although I can wear a 12.5 in the Wave Rider). He told me not to bother sending them back but just see if I could trade them at a store for a 12 or for something I like. So if anyone wants to buy them, make me an offer, or if you have a shoe, preferably a light trainer racer, that you have only worn like once or twice and decided you don't like, in a size 12, I might trade for them. Or, if by any chance someone will just trade me a size 12 Spacer for them, that would be great. It is a fine shoe and folks who like a soft, fairly light low profile flat should like them. They are unworn and still in the box.
Email me if interested.
