A superb quality footwear brand, that makes excellent well fitting sandals. KEEN, Inc. is an American shoe manufacturing company based in Portland, Oregon. Founded in 2003 by Martin Keen and Rory Fuerst. The first KEEN shoes were invented to develop a sandal that could also protect the toes—they feature a signature thick black bumper covering the toes. They found a ready market in sailing and other outdoor and water activities. KEEN Footwear now offers shoes for many outdoor activities as well as casual shoes.
