bought new boots and waders on the weekend, got a smoking deal--decided to go with rubber soles---wellll in rivers where its sandy they are great, went to a river with rocky bottom with some sludge on the rocks and seriously felt like i was filming blades of glory 2....i ended up stepping on a flat rock which migh as well have been a slip and slide---fell into the water face and all...i want to be able to out felt on these or make them a little stickier...any suggestions..and for the sake of my sanity do not suggest i buy simms....thanks folks
