I'm planning a two-day hike, camping on the sand on the beach in South Florida, trying out some new stuff. I'm thinking this FLAT, non-technical walk might not require my Columbia hiking boots. Anyone (such as desert hikers) have recommendations on good hiking footwear for sand?

There might be a little surf-wading so the shoes might get wet a few times. I plan on having a 15-18 pound pack. I've always worn high-top hiking boots; this might be a good time to try a low, lightweight hiking shoe (in this case, two of them.) Any suggestions?
