I received a pair of the Free 4.0 shoes as a birthday gift a year ago and those shoes were my regular / gym shoes for 365 days. After so much wear, the tongue of the shoe got to the point were it separated from the shoe itself. I tried to sew it back but I was only delaying the inevitable. They have served me well for a year but it was time to move on.
I'm not one to strictly buy a name brand but these shoes are simply everything I want in a pair. Light and comfortable these are my new go to shoe rain or shine. They also improved the tongue to be more separate from the shoe itself so it can't wear itself apart.
