I decided on these sandals for a recent trip to Haiti.  I chose them because they seemed less bulky than Chaco's.  I wore these sandals for 6 days straight, and they were perfect!  Easy to adjust, comfortable and offered a perfect amount of support.  I wore these walking on rocky terrain the entire week, and they were great to wear in the Caribbean to protect my feet from sea urchins.  All in all a great shoe!
