Keen Footwear is an American shoe manufacturing company 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.

As Keen has grown, there have been many changes, including the addition of a variety of footwear styles to their previous assortment, growing their casual business quickly, adding cold weather footwear, and a line of bags and socks.
