These boots are awesome! One season of over 50 days in them and they still look like new! The break in period wasn't too long and the stiffeners work surprisingly well. I would say a 4 flex without and a 7/8 with the stiffeners. The storm shield also works really well when dealing with slush. The one improvement I would make is having a softer foot bed for my 10 hour days.
