Also called galoshes by some. This period of the year tends to bring lots of rain to Seattle, and is usually when I pull out my SWIMS. They work well enough in protecting my shoes, and the insides are lined with a soft material that helps with taking them on and off. Allen Edmonds sells them on their site for just under $100 which is not too bad, versus other places that sell them for around $130. I would also recommend following Allen Edmonds sizing advice for these (a size 12US should get XXL for example).

John Lobb Paris sells some fancy overshoes as well, but are ridiculously expensive at 120GBP or so for a pair.

Yellow seems like it would be a fun color to get, but it also feels like a slippery slope down a dandy path that I’d rather not go.
