No, you wont find them easily in Seattle. I actually had to wait to go to Las Vegas to find them. But there is a place in Ballard called Market Street Shoes that I noticed had them last weekend. They also carry Alife, which is nice. And the boots dont look good with skinny jeans (at least with JR Calis).
actually you can go right across the lake to the east side, to bellevue square. they have a clark's store there.
endless.com also had the desert boots for $60 USD for a while, but now it's gone, sadly.
