Most of the vets here know about this, but I discovered (almost the hard way) last summer that going from the water, to sand or light gravel and then to standing on a dry rock is NEVER a good idea. A guide noticed I was wearing felt sole hip boots when we were fishing the Bruneau River (mountain whitefish and wild rainbows) when I stepped out onto some dry sand. He advised me not to step on any of the dry rocks nearby for good reason. With the sand now on the bottom of the felt it creates a non-friction dry surface against the dry rock and you'll go sliding off.

If I'd have had a cleated felt it might not have been much of an issue but these were straight felt. Just thought I'd pass this along as a reminder. It's one of those things we don't think about. A lot of people like me get felt for walking along and over the slick rocks and don't think about what to do once OUT of the water.
