I can not speak directly of the NRS boots.
But my Choata Lite Mucklucks worn over my NRS wetsuit take on almost no water during relatively easy stepouts/swims. Less than 1/4 cup in my last 10 minutes bouncing down the Farmington below Goodwin Damn.
It's easy enough to take a swim in yours and see how that works for you.
