1. It doesn't start on game day. It starts at practice.
Nobody gets a blister like that from one game. A skate is stiff and laced tight, so the boot doesn't give. Your foot does. Every push-off slides the front of it across the same spot inside the boot, shift after shift, practice after practice. By game day the damage is already days old. The boot isn't just pressing on your foot. It's dragging.
