I fish some small creeks and for,several years have used Ice Creepers. They look like a pair of sandals, very firm synthetic rubber with web straps and Velcro , and a worn out pair of sneakers. Creepers are studded with hex headed sheet metal screws. I walk on loose stone , sized from gravel to the size of a king size bed. Not to mention the solid rock bottoms. Trust them more than my felt bottom shoes.
