Simms Alumibite Studs Demo 

Great review thanks for the info. I hate slipping and falling down, I am installing them on my Headwaters boots.

Good products. Found that the studs sometimes come out so adding some adhesive before inserting the stud is a help. Wouldn't go without studs with this vibram sole shoe. Did once, and it was slippery. Have purchased snowmobile or atv tire traction screws, which you can buy by the hundreds for a very low price and they will perform similarly. I have this exact Simms wading shoe. Good shoe, but the liner inside is cloth. The cloth rots from immersion in water and had enough tears that I eventually had to cut it out. Simms might look for a different liner.

You get the same effect for a lot less using hardware store size #12 hex head stainless steel screws, 1/2" or 3/8". Home depot. Cost a fraction as much. They all wear out, regardless of that fancy shape.

They fall out of the boots constantly. Day 1 I lost 1/3rd of them. My orvis boots never lost studs this frequently. Simms says I’m even under screwing or over screwing

Will these work on ice helping you get traction

Can these be used with felt soled boots??

what cleats better for algae-covered rocks?

No. Hard rocks bite into the aluminum.. and the hardbites bite into soft rock.
