Waterproof split-toe socks: you would THINK the Japanese (& others) who wear nothing but thongs would have long since invented them, but it seems they do NOT exist! However, I have modified my ultralight thongs into ultralight adjustable ‘thandels’ (@ 61 grams per pair) so that I can wear them with my seal skin waterproof socks making them into a useful pair of waterproof hut booties with very tough soles. The commercial alternative are these at 1.7 oz per pair. Their down socks sound great too: https://goosefeetgear.com/products/2-waterproof-over-booties
