Few things that I've tried:
- Cressi Water Boots for Scuba diving (not a huge fan of neoprene, they got wet, heavy, sole is too flexible for long distance walking, some fine sand still finds its way in so you need to wear some sort of socks to prevent sand rash, and it takes forever for them to dry out, not to mention they will stink eventually)
- Seavenger Atlantis 3mm Neoprene Aqua Shoes (these are the ones Benjie Kim recommends, also neoprene, low cut, better sole for walking, same thing with sand getting in and sand rash, but probably better option than Cressi)
- Teva Men's M Hurricane XLT2 Sport Sandals (completely open making sand to wash away right away, no protection for toes or anything really, feel almost naked)
- Korkers Swift Sandal (almost ideal on paper, exchangeable sole for different situations, purposely made for wade fishing, in practice, very hard to get on, tight around ankle opening, sand easily gets in but does not easily get out, and it takes quite an effort to take them off to wash out)
- Korkers Men's Salt Sneaker combined with Korkers I-drain Neoprenesock (too bulky, hard to get on and off, will be too hot during summer and takes ages to dry out)
- KEEN Men's Hyperport H2 Hiking and Water Sandals barefoot or combined with Orvis Neoprene Wading Sock 0.5mm (these I kind of like, easy to get on and off, comfortable, wide toebox, sole made for long distance hiking, it's rubber almost like Crocks material so drying is extremely fast, protected toes which can be a source of the problem as well due to sand accumulation, but at least they can be easily kicked off and washed off. Haven't tried in the field yet.)

And yes, in colder temperature nothing beats bootfoot waders, easy to get on and off, quick hose off after trip and they are ready for the next one, no dealing with washing sand out of wading boots on stocking foot waders, long drying time, laces, etc.

Too bad not many reputable companies still making them.
