Love my MW7s and these look very good too. I put mine on early on in the fall and wear them relatively late into the spring. Comfy feet are nice and I while I certainly sweat in them, I have never said "my feet are too warm".
Make sure you have a boot dryer! If you go out in full on rain, eventually your feet will still get wet from water running down socks (I'm hoping pants might resolve this?). In that case, your shoes will take days to dry without some airflow through them. I tend to put mine on the dryer regardless.
