I ordered Keen Seacamp and Newport in exactly the same size and color to compare, and pick the best fit for my 7yo.
Seacamp seems more slender, lighter and airier, and at a first glance, I liked it better than the heavier Newport. However, Seaport only has two straps for the elastic shoelace, and does not adjust to the foot as well as Newport, which has three straps.
Newport can be tightened all the way to the toes, providing a much better foot support for narrower feet.
After running loops around the livingroom in both pairs, my child said Newports were much more comfortable, and that's what we kept.
This supportive sandal can take anything a kid can dish out. An adjustable hook-and-loop strap lets kids put them on themselves, and quick-drying webbing is perfect in and out of the water.
