BerghausWomen's Supalite Ii Waterproof Hiking Boots | Lightweight | Durable | Comfortable | Vibram | Gore Tex High Rise

These good quality boots come with poor quality laces that are too short and slip. Any recomendations for good non slip replacements?

How long will they last , stay waterproof ?

Are they comfortable from the beginning? Do they need breaking in?

The inside of my existing supalite boots is soft leather. Description here says inside is manmade. Is the interior around the foot soft leather?
