Bought the Kinvara's for my sister.  Have used Saucony shoes since high school and preferred their footwear for most of my running career (just an avid runner, not an actual paid runner).  They seem to use a material similar to crocs for the tread which makes these shoes light weight and comfortable.  My sister complained about her other shoes and I though it was time to replace them for something for comfortable.  She enjoys them and uses them when taking my nephew for a stroll around the "loop" where she lives.
