Baffin Swamp Buggy's are 3/4 height, rugged water boots. I use them in my sea kayak; they have a wide fitting so they are all-day comfortable, plus give you stability and grip walking on rocks and uneven surfaces. They drain almost instantly; dry quickly and are easy to keep clean. And the cord and toggle fastening is more convenient than laces.
I wear fleece socks under dry-suit socks which is all quite bulky, so buy large. I'm normally UK size 8 (42), so I bought a 9 (43) - which was a good fit.
