i walk trails where i live and have purchased saucony shoes for several years.  the fit is good and they are comfortable, but the small rubber piece that fits in the outside insole on the bottom of the shoe has come off on both shoes after only a few  times walking in them.  They are just glued on pieces so i don't know their actual function.  on the picture of the shoe you will see the outer insole piece i am talking about.  i will check the next pair i buy before wearing them.
