Hey guys,
I have a special pair of waders I use for surf fishing. They are an inexpensive pair of "boot foot" breathables. One of the difficulties of using stocking foot waders in the surf is the constant abrading of the neoprene by sand that gets trapped between your stocking foot and your booties, wading boots, tennis shoes etc., etc., I ruined two pair of breathable stocking foots. The sand wore the neoprene until they began to leak in the toe and heal. The "boot foots" although a bit clunky, are virtually impervious to the sand, and eliminates the need for all the rest of the gear, much simpler. I like the Crocs idea (they weren't around when I was heavy into surf fishing) Believe me I tried my best to keep the sand out of my boots shoes and what not, but to no avail. So now I just use my boot foot clunkers.... LOL
At very least if you use wading boots or booties, a good snug fitting set of gravel guards can help...
