Take them to Red Wing they are warrentied for a year I believe.
If you like the way the boot fits since you broke the leather in, you can get them re-soled for about $100. If not, you can use saddle soap to speed the break in process of a new pair.
Had my resoled free the first time . The second time i changed the sole , had the same sole 2 years and counting no problem
