I have been wearing my Keen La Paz sandals nearly non-stop since receiving them.  They are very light weight and I like them enough that I am going to buy a second pair.  It is so hard to find a light weight yet durable and comfortable sandal that is equally at home on a beach or a sidewalk.  Love them!  They do run large so best to go down a half or even full size from regular footwear sizing.  Only complaint is the sizing strap on the top of the ankle will not stay in place and needs adjustment from time to time.  Other than that just a nice all around sandal.
