Not sure if they are "warm" boots or what style you want but I have two pairs from Aquatalia that I snagged on sale a few years ago ($125 and $170; usually $395) and they are nice quality, waterproof leather for in-between weather, look professional and are comfy. I just wear smartwool or darntough merino socks with them for warmth. I have the "Fuoco" style in tan and black.
