don't get larger they will just slip and rub causing blisters
get thick wool gumboot socks they pad out pressure spots and wick away sweat while staying dry enough to not soften your skin. And leather insoles as they form to the bottom of your foot so the pressure is spread as much as possible
next time you need new boots get leather uppers with no lining
