This is my third pair of this sandal, which is the most comfortable, excellent walking/sport/everyday sandal I've ever owned.  The footbed is amazingly supportive, and the straps - adjustable in three areas - provide a perfect custom fit.  I can walk five miles in a brand new pair - absolutely no breaking in time is required.  These definitely look like sport sandals, and I had originally intended to use them exclusively for outdoor activities and to change into something more attractive for every day use.  However, shortly after acquiring my first pair I found myself wearing them around the clock for almost every activity, indoors and out.  This is truly an outstanding best-in-class product.
