I've been purchasing Asics running shoes for five years now and this model is fantastic.  I was hoping to buy another pair of the Cumulus 12s, but could not find any in my size; therefore, I ordered the Cumulus 13s.  It is a fantastic shoe!  Very comfortable - after breaking them in for a fews days I went on my first run and they were astonishingly comfortable.  As with all running shoes make sure you have the right size!!!
