I fully expect to wear these all winter, snow or not.  Most of the fall, too.  I got the leather because I didn't want to deal with suede.  I fully plan on water proofing them for the winter.  When you're breaking them in, don't wear them on a walk.  The heel is a bit deep and allows my heel to slip around a bit, leading to blisters if going long distances.  I fully expect that they will fit perfectly after being broken in.  I followed another reviewer's advice and got a half size down from what I'd normally buy in other brands.
