Thanks Ard. I was thinking about Simms Star Cleat or Alumibite studs. The Alumibites stand WAY proud of the Vibram lugs, and that looks awkward. Can you feel the Grip studs pushing into the sole of your foot? Do either brand effect your grip on dry rocks: more or less slippery? Is one noisier than the other. The bluegills I fish for are spooky.
Hope you had a good day on the river!
