Have you ever tried any of the tropical salt sneaker designs for up here?
Edit: Just looked at the latest salt sneaker from Simms and it's actually listed as heavier than the FreeSalt boot. Looking at the two it's hard to see how that could be though.
I tried some Simms flats boots years ago. Even with a size 14, they were super narrow and didn’t fit well with my stocking foot waders, so I returned them before ever wearing them in the beach.
