THESE BOOTS WERE MADE FOR WALKING

And that's just what they'll do after a wad of shoe goo. To fix soles that come apart stuff boot with paper or rags, glue inner soul to boot first then let set. After that's dry then glue boot to soul and apply a clamp or 2 just enough for good even pressure. Tip- don't put boots near heater for 3 days as boot leather will shrink! To fix that problem soak boots in hot water for 30min then put on and keep on for a day or 3! Should do the trick! G'day mate
