I'm buying the Keen Whisper so my feet can get wet and dry quickly on water rides, rain. My 18 year old daughter has very flat feet. Is here any water friendly type sandle that has good arch support for women with flat feet? I don't want her to have to wear tennis shoes that will be wet all day.

. I see every viewpoint possible on this subject on the internet and not sure what is best for me. Good luck OP.
We totally disagree that they are awesome shoes - we think they are the worst, and we have Salamon, Teva, NB and Merriills, as well.
