Boots for fat calfs

Very curious if anyone knows of any type of winter boots preferably not uggs that will be loose and comfy for plus size girls who have very chunky calf's. I can't find or fit many boots now and when I'm further along I know it will be super hard with swelling all boots I have tried look like they are about to pop off of my legs and u can forget trying to stuff pants down into them 😭 I really like rain boots never tried a pair on though
