My experience with muck boots is they are seasonal throw aways. I'm looking at a pair right now in my shop office that have the soles 75% delaminated from the boots.
These are not the only ones that have come apart on me. I think if you carry them in a backpack to your hunting spot, then carefully put them on once you are ready to be seated, remove before standing.... they will do well for many months, possibly years.
