Waterproof, warm and smart boots needed for work

[PlayingSolitaire]

Please help me!

I have started working in an office which is often freezing as the door to the outside is left open. Outside the office it is very muddy and wet and there is a short walk to/from my car and I sometimes need to walk around in the mud/wet more than this. However, despite all this I have a smart/casual dress code (in no jeans). So, I am looking for:

Boots which are either calf length or knee length
Black
Smartish (not Wellingtons, but don't have to be super smart)
Probably leather so I can clean off the mud easily
Warmly lined (fleece, faux fur?)
Waterproof
Able to drive when wearing them

I think that's all I need!! Can anyone recommend anything?

Oh no, wrong poster - I'll shut up. For you OP, the Merrell link may help!

I've just bought some Hotter gore-tex boots that are comfy and relatively smart.

They also have some that are fleecy lined, not sure how waterproof they are compared to the goretex ones though.

You have to pick and choose - some of the styles are very grannyish. But there are some that are fairly reasonable and they seem to have comfort built in as one of their things that is important - which for so many other shoe/boot makers seems to be a loooong way down the list after design and other stuff!
