Bootfoot waders with a drytop would be a good choice, but I just plan on being wet.
In my experience Goretex doesn't cut it, so I've gone low-tech with a PVC slicker.... clinched up as well as possible
A wading belt over the waders and a second belt (possibly the stripping basket belt) over the slicker
You'll quickly find that bootfoots are the way to go. The surf forces sand into every crevice in wading boots, gators or not.
I use to duct tape my gators down ..... made no difference
The simpler the outfit, the more skill it takes to manage it, and the more pleasure one gets in his achievements.
