I'm gonna take a close look at that Sailrite video.
Probably outside the box you're looking at, but: Spurred by a bout of plantar fasciitis, I threw out the worn-out (and filthy) rugs on
Wild and covered the whole sole with EVA foam gym mats. Easy on the feet, add some wintertime insulation, and don't absorb dirt. (No I didn't use any of these interesting colors - just black.)
They cut to shape easily with a bread knife. Easy to peel back a small section to access bilge hatches.
They have no "backing" so don't grip the floor particularly well. If they fill the space, it's pretty stable, but if the edges are free and water gets underneath, they'll slide right out from under when you step on them. I have them in the cockpit too, but have to be wary in a seaway.
They're also handy to just rip up a square when an emergency fender or padding is needed on deck for something.
On Arcturus, I've got some pretty good non-slip easy-wash mats that came from my Mom's assisted living center. The staff brought them in when she was having severe difficulties with bathroom functions. But they don't exactly fit the space and they still absorb dirt. The closest match I can find for them is door mats, but that's not quite it. Outdoor rug?
