I really need a pair of new winter boots, but am struggling a bit with what to get as I'm due in January. I need them to be nice enough to wear to work, and most of my maternity wardrobe is dresses. But it also can snow a lot here, so I need good traction for walking around in them nine months pregnant. And I have no idea how much I should expect my feet and calves to swell, and assume I need something that comes on and off easy. Any moms with winter babies find a boot they loved?
