I also use those Simms Guard socks with my normal boots I use with my waders and love them. Imo, don't wet wade with Crocs unless it is a low gradient stream with very easy wading. One of the few times I've tried wet wading with crocs was actually in Colorado. I'll never do that again. The stream was high, fast, and filled with big boulders which made for difficult wading. At one point I actually lost one in fast water and while going after the one the other came off!! I retrieved them both thankfully. And they don't protect you're ankles from rocks and such.
