The idea of Allie bars on the bottom of boots is not new by a long shot. Dan Bailey had what they called 'Stream cleats' which were an 'over shoe' you put on over your regular wading boot. The bottoms were 'wwwww' shaped bars. 'Clunkie' to just walk around in, but those bars will stick to any river bottom .... and I do mean any
Allie is a soft metal and there for grab/cuts through just about anything. Run a metal drift boat solidly on a rock and you'll see what I mean.
Enough metal on these to do the job? Time, and someone with an extra $200+ bucks will have to report back on that. Candidly, you could take a 1/4'' allie bar and cut off sections to fit your existing felt bottom boots. Drill screw holes in the sections and apply with 8 x 1/2" screws and you're good to go for pennies on the dollar.
