Re: Which New Wading Boot?
Simms fan here too. Went with the G4s recently. Vibram with screw in studs, though I have yet to use the studs. The boots are serious tanks and, as Russell says, wide of sole. Try them on before buying, if you can, to get the size right.
Shortly after buying them, I picked up a pair of felt Freestones at a ridiculously cheap price on one of the online clearance sites - just before Simms announced its return to felt. Perfect for my tricky footing warm water bass river. Felt bites like nothing else.
