After much reviewing my daughter and I got these to wear on the big island of Hawaii hiking through raw lava, snorkeling, to the top of Mauna Kea, etc.  I ended up wearing them exclusively the whole trip they are so comfortable.  They dry quickly, and are incredibly rugged, held up to sharp lava without even looking like they were worn, I thnm my other shoes would have run away screaming :).

These are about comfort and ability, which has a tule all it's own. ;)
