Keen Zerraport

Backcountry.com says:
Want to take your sandals out on the trail but afraid they can't stand up to the rocks, uneven terrain, and dirt? Slip on the Keen Zerraport Sandal and take on any trail. Keen took a sandal design and gave it a burly trail hiking sole so you get the cooling benefits of a sandal and the support of a hiker. A compression molded EVA midsole cushions your foot on that uneven terrain, and the dual adjust webbing support system gives you a custom fit and keeps your foot where it should be. Keen gave the Zerraport Sandals multi-directional outsole lugs with razor siping, which grabs slippery river rocks and rocky trails alike.
