For those of you who are active duty or retired military, check out your nearest Army post.  At the military clothing sales store, I got some boots very similar to these at a much more reasonable price.  Used them with some satisfaction on my last Quetico trip and on several river trips in Colo.  In general, satisfied with them.  My biggest complaint is that in muddy water, my variant of the boots let in silt that permeated the socks.  Kept sand out OK, but not the finer silt suspended in the water.  Never could get the socks to dry on the trip, and never could get them clean--NEVER.  I was using them in Fall, and I found I could use them both in boat and on portages. My feet stayed warm but damp, and I got acceptable ankle support. I brought a pair of ordinary athletic shoes for around camp--because the boots never did fully dry out.  Again, the ones you are describing might handle that better.   I brought a separate pair of socks for each day and changed them when the paddling day was over. If it is not cold, I prefer to paddle without socks and so do not use these--but then I take the time to change for portages, except for easy, short portages.  I just don't like wet socks--even wool ones with liners.
