OS,
i've had good luck with the TEVA brand water shoes, not to be confused with there sandals

i check the web and get a deal on the last year model.
I got 3 yrs on first pair, still look good, but sole has lost some grip.
this year i got the Gamma pro for $30 on sale.
Only drawback, is there only ankle height, same as running shoes??
Something, you may or may not know??
WHEN people talk about ankle support, what there really telling you is they have WEAKNESS" in there supporting muscles around the foot area.
IF you have that problem and want to fix it and not just hide it with high boots and restrictive lacing techniques, you can go to a running store and buy a balance trainer and that will fix you right up!
its basically a circular piece of wood with a central pivot point that you can adjust for angle.
The idea is to strengthen the weak muscles by balancing yourself on it a few minutes each day.
In over 25 yrs of exercise classes, aerobics,step and outdoor pursuits, i've never worn a shoe higher than ankle height and never had a problem??
TEVA shoes are also sticky as all get out, so that helps with the bashing your feet can endure, if your slipping and sliding down the portage trail!!
I know your a gore-tex sock guy, so if worse comes to worse, you have a camp fishing day shoe that will double as portage shoe if you need it
