Re: Sandal-type Boat Shoes
I bought a pair of TEVA sandals at Academy Sports in April that looked like Keens, but were about half the cost. So far I love them. They have held up fine, and are very comfortable, even when walking on rocky shorelines. They have also seem to have a pretty good grip, although I haven't had them out on a really rough day.
You definitely want something with some toe protection, not a regular flat sandal. Otherwise I agree with Chef2sail that it's a question of when, not whether, you'll be visiting the emergency room.
