Simms Riprap Wading Shoe
I got a pair of these last week and tried them yesterday.
I love these. I use them for wet wading, not over stocking-foot waders.
They're light, stick like glue on the rocks and are designed so they don't let much sand or gravel inside. They're also comfortable on the walk to/from the fishing spot.
The biggest problem I had was overconfidence. They stuck so well that I started to get less careful about where and how I put my feet going from rock to rock. I'm 66, and was fishing alone, so a certain amount of trepidation is a good thing.
