Having lived in Seattle, the rain is often more of a heavy mist and less a major down pour. I have worn my suede shoes (I own several pairs) in all kinds of weather and find that leather and suede can get wet, you just have to let them air out and keep them away from heat. I also treat my suede with silicon and use shoe trees. My favorite pair for all weather use are oxfords from Heschung in a dark brown (called oak) with a rubber sole. These easily pass for a dress shoe in all but the most dressy settings http://www.heschung.com/ah07/heschung.php
see under "classique Goodyear" the Asterec model
I wore these all over Paris and Rome one rainy December. Suede is wonderful, it breathers very well, it is light weight, very flexible and comfortable. Don't be afraid of suede....go for a pair. And, if you are hesitant, get the darker color brown and a can of silicon spray.
