Wading boots stud install; Old School Style 

I took some viet Kong Jungle boots and screwed in screws that had angled heads rather than rounded heads. They worked well, but tore out after a couple of trips. I am not certain if you want a really hard carbide type screw (harder than the rock) or a softer screw? the old fashioned stream cleats I have been wearing down over the last 8 seasons after inheriting them from my dad worked really well, but they were made of aluminum which is pretty soft, and they are rectangular box style studs that run about 1 inch by 1/4 inch... They leave silver marks ion the river rocks, but man do they grab well. I've nearly worn them smooth, so I am trying to figure out another way... The strap on carbide ice soles look good, but I am afraid that since the ice is soft, and the studs are hard, i'll be scrambling. I think a softer donor metal works better in river wading applications. Which means aluminum.

These screws to soft by Rockwell hardness scale to work.

Thanks for this.

Thanks for this. How did they work out? What is the purpose of the silicone?
