Love these shows, feet got old and spread out necessitating move to 4E's and the New Balance Brand 10 years ago.  I try to stay within styles though as the styles have different sizes.  I usually go to a B&M store to get first pair and then use Amazon to get others (I'm an hour from a real store and driving hurts my back).  The cross trainers above are larger than the tennis shoe version (623X tennis shoes) I had earlier (out of stock, discontinued-don't remember) by about 1/2 size.  Although Amazon has a generous return policy, I had to wear them a bit to find out they were over sized.  Still a great shoe and holds up well.
