I purchased these
Tropicfeel Lava shoes last fall for two reasons. First, my wife and I spent many weeks in SE Asia this past winter and I wanted a lightweight shoe that would be good for walking and good for being around water. Second, in the endless quest for the perfect wetfoot wear I thought they might work well for canoe tripping.
They worked well in Asia. I really appreciated having a shoe that could serve many purposes so I didn't need to pack extra footwear.
I just returned from an eight-day trip in Quetico. The shoes worked as well as I had hoped they would. They've got a broad enough sole to be stable, they dry more quickly than anything else I've tried short of sandals or crocs, and they had excellent grip on the rocks.
FYI, I replaced the laces that come with the shoes with standard golf-shoe tie-up laces.
