After using these sandals for several different water activities I am very satisfied with my purchase.  I have spent several hours at a time in these sandals and they have remained comfortable wear.  They provide good traction for walking in and around rivers and wet surfaces.  I have had no problems with the arch support.  They are easy to get on and off.  I love the toe protection from these style of sandal.  They seem to be built of pretty good quality materials. For the price (I got mine for around $45), these sandals are a good deal.
