fwiw:
Used  a pair of 'Altma 3LC',   (You need to Login or Register
jungle boots going up Stuart River and out Horse River/Mudro. Wet footed all landings and waded thru several rapids. Some long portages and the climb from Sandpit to Mudro.
Lots of traction on all surfaces except moss/slime covered rocks underwater. Full shank meant walking over sharp pointy rocks and such was no trouble. Good protection over and above the ankle. Drained well. Worn with Smartwool socks. Good fit, I take 8 1/2 EEE size, bought 9 wide. Had room for liner socks and heavy hiking socks. Dried out overnite, faster than the wool socks.
A bit heavy, but are now my paddling boots of choice.
