I usually buy my running shoes a local store, but I saved almost $30 ordering them on Amazon.  I doubt I will go back to the local store anytime soon.
I love these shoes, because I have a neutral foot and they fit perfectly.  I used to have knee paid when I ran in a different brand/style running shoe, but I don't have any pain with these shoes.  I also have found they last much longer than the 400-500 miles recommended for a shoe.
