It was 13 degrees F where I live today and we are not yet into winter temps. That said, tall boots aren't a personal wardrobe essential for me. For truly deep snows where it dumps a couple of feet or even a regular 8" storm, I have a pair of calf-covering snowpack boots that I wear for shoveling or if I have to go out before the roads and sidewalks are cared for. For much of the year they got back and forth between my car and the house just in case I'd have an emergency, like being stranded on the unplowed shoulder -- - but that is because I live in a rural area and have compromised circulation in my feet, and they get cold even in those boots in dangerous temps.
For everyday, I have mid-calf boots, and ankle booties that get worn a ton depending on the pants I'm wearing (I'm almost exclusively a pants-wearer in the cold, which might affect my prefferences, but my legs are the least cold sensitive part of my body, so good tights go a long way).
I also have these nifty things called gators--- mine are slim and solid black. Basically they are waterproof nylon with elastic or drawstrings at the top and bottom and a strap that goes in the knotch of the heel of a boot. They turn any short boot into a tall boot and take about 30 seconds to put on (wouldn't work for massive shopping trips, but they are perfect for going to work, etc.) and fold up smaller than a slouchy beanie, plus they dry almost instantly.
Despite this, I usually don't have issues with snow in my boots, or even wet hems. I don't know if it is our lower-moisture content snow (CO-- know for its "powder") or what but I rarely have problems with wet hems, even bootcuts, they dry fast and our snow is either dirty but plowed or very clean. Plus, walks tend to melt fast in our sunny climate from the radiant solar heat if you attempt snow removal. Plus, in our dry climate wet hems dry fast.
On really icky days I will wear a pair of gortex mid-calf combat boots that I can pop on under jeans and are comfy enough to wear all day if needed, but are 10x smaller to transport than snowboots, and they double as awesome hiking and work boots the rest of the year.
