Baffin for sure. I even hike in mine in the winter. I still like to wear wool socks with them, but I wear wool socks all year round.

If you are a sheet of sheer ice though, even the best boots will need some shoe chains. In the city, YakTrax did the job for me, size up when putting them over snow boots. For hiking, Hillsound makes an excellent microspike, but I would absolutely not wear them in the city or with pavement.
