These are among my favorite summer shoes.  I have at least 6 pairs of various Keen styles.  I love the comfort, and the toe-protection.  They support better and contour to your foot better than a flip-flop; can be worn in water, on the boat, with casual clothes, and are very comfortable for walking.  I have hiked in rain-forests, and walked on city streets with NEVER a blister or discomfort.  This style does have a flip-flop type of toe separation inside (not visible when worn), but it does not rub or cut.  These sandals do not slip around on your foot.  The blue-color is denim friendly, but works like a neutral.  They last well, even when worn on the sand or water.  Well worth the cost, yet less than many similar styles found in boating stores.
