I originally had the previous version of the Cumulus -- it was the best shoe I had ever had.  I made a mistake in ordering from Amazon without trying the shoe out locally first. This version is noticeably more narrow, and I don't use it to run with.  (It pinches and makes my toes a little numb, even after a &#34;breaking in&#34; period.  I recommend getting shoes from Amazon (the prices can be much better!) but get your shoe sized and fitted at a specialty store first to be sure you aren't stuck with an expensive running shoe you only wear for short trips to the grocery store.
