I bought this shoe in 2011 and have run in them almost every day. I've worn them down to nothing, all the letters and logos have worn off and I have been online searching for this exact model for three days. Now that I've found it, I'm ordering several pairs so that I can wear them for as many more years as possible. They fit perfectly in width and length, I didn't have to break them in at all, they were very sturdy lasting longer than any other shoes I've run in, I just can't say enough about how great they've been!  I have normal arches, my feet are just slightly wider than the average woman, and I supinate a little bit but these were fantastic for me in every way. Awesome, awesome shoe! No knee problems, no ankle problems, no problems at all. I wish I could give a higher rating.
