I was looking for shoes to fit a high arch and neutral pronation.  Saucony's site identified these as fitting that profile.  Had to make a switch from Asics because of their change in the cushioning of the Gel-Nimbus.  These Grid Cohension's are a great substitute!  So far, they have been as flexible as my supinated foot needs plus as cushioned as I wanted.  They don't have quite as much toe-box structure as some of Soucany's higher priced models.  But for the price they are terrific.
