A lot of places are putting these shoes on sale/closeout. Is there a new model coming out? I'm tempted to buy these shoes but most of the reviews I've read on it say they don't last long (200-300 miles tops). I'm looking for a shoe to use 2-3 times a week for 10-13 milers on mostly hard surface. I currently just started running with the Brooks Launch but am looking for something to rotate them with.
