In florida I only use a thin lycra sock. I also dont put on my socks and fins until I'm in the water. Sand in my fin is the worst.
Althought I dont wear neoprene socks Ive checked out some of Dans speardiver socks and they are exceptionally well thought out and well made like all of Dans products. I think they are what youre looking for.
Open cell inside except the bottom of foot is lined so you dont slip walking. Plus the bottom is lined in wetsuit elbow pad so they will hold up. They come in camo colors too.
