I had the sidi gore tex boots. They’re waterproof but at ankle height, they’re pretty useless as water immediately enters over the top and soaks the whole foot. I haven’t bothered with winter boots in a couple of years now.
Personally I would just look for a couple of overshoes that can be stacked. One for warmth, one for dry. It needs to be calf height and tight at the calves to keep your feet dry.
I have tried so many, even officially testing new Rapha ones and I've never found one that does both warm and completely waterproof.
I used these through last winter and they were amazing.

The first waterproof overshoes that I've actually had dry feet in. They usually let water in the bottom or over the top of the cuff but not these, the extra length is the key bit.
They are flexible enough that I can put them over my shoes even with toe covers on and they do keep my feet a bit warmer anyway due to blocking all the wind and not letting much warm air out.
