I had previously ran in 580's- could not buy them any more. I am 200lb runner an bought pair of 587's on 09-3-12- On a run yesterday the rubber sole on heel came off shoe. I contacted New Balance and they are sending me another pair. I am blown away by poor quality of this shoe. I am glad it did not happen in the half marathon in 3wks. Will try out other brands after race. I would have expected more from for a shoe made for a heavier runner!
