When I lived in Alaska the natives all just laughed at the idea of shooting at a grizzly with a pistol ... unless you wanted to piss him off so he'd kill you faster. A black bear ... ok.
^^ Good plan.
For the OP.
Once you confirm new boots fit I'd further recommend then wearing them hiking ALOT to break them in before taking them on a hunt.
In the future I’d recommend wearing new boots around the house on carpet for a little while before going outside or applying any leather conditioner.
Carpet wont cause any wear and you’ll be able to return them if necessary.
