These are the sandals you want if you have high arches. Their arch support is superior. The strapping system is complex but worth learning. The trailing strap off to the side is too long (too much slack), but even though it falls off to the side, it doesn't bother me or get in the way, despite the way it might look. I wear a men's 7. It would be nice if they made a 6, as the footbed is long. The boy's 6 is not a good solution, as it does not have the volume and heft of the men's sandal.
