There is nothing straightforward about this. The choice of saltwater footwear is so personal it nearly defies recommendation. But one can offer parameters.
Do you need fitting out for a dedicated wading trip or will you be mostly boat fishing with occasional forays into the water? What conditions are to be expected? Will you be walking nice hard sand flats or a mixture, with soft suck holes and/or mud, mixed shells and coral pieces, and horrid limestone ledges?
And what about other threats? Standard garb for wading Texas flats is stingray guards, either strap-on or now incorporated into slightly higher wading boots or booties. What’s your physical hot/cold comfort zone and personal conditioning? If you come from a sit-down office job sporting tender white feet, don’t expect to wade barefoot and match a native island guide with leathery sole calluses.
