My best running years are behind me but I still like and need to do some jogging - aiming for 3 miles 3x a week.  I shopped in several retail stores.  When I shop for running shoes (not often) I like to talk to a reasonably knowledgeable shoe salesman.  They apparently became extinct when I wasn't watching.  I was totally ignored in each store.  So I decided to buy them on Amazon after doing a little research on my own.  I'm totally pleased by the timely delivery, the good fit and comfort and free shipping with Amazon Prime.  And I have no sympathy with retailers who complain Amazon is killing them.
