Socks with Sandals has always been a debatable trend but when in the Pacific Northwest, specifically Oregon, all footwear-fashion rules go out the window. I remember being fascinated with my first pair of Tevas as a young boy traversing sea rocks and sand and am still a fan of the strappy-fabric-velcro man sandal.
