I’m another Simms Rivershed guy and am extremely pleased. Mine are the First Gen version with Aquastealth and studs. Making a transition from felt to rubber came with a brief period of adjustment time but I’m glad I took the plunge.
I fish mostly small backcountry streams, larger creeks/rivers with rough freestone stream terrain and am quite pleased with their grip, support and comfort. What I love most is that I can fish in the winter and snow no longer sticks to my boots! ;D Also love that they don’t hold much if any water weight.
