make sure you bring the trekkers flpaddler.  i have Keens very similar to the karmas you just ordered....and if you wetfoot, i can almost guarantee you wont be happy with them.   sorry.  gravel and sand get sucked in like you wouldnt believe!   mine are now my camp shoes.  infact, they are my "slippers" at home right now.   i thought they would be the answer...but for me, they werent.

my ankles are still good, so my portage/canoeing boots are cheapa** rubber slop boots from the mans mall.  15" height.  have to admit tho.....i cant wait to take them off when camp is reached!!!!  which, im sure...is the same feeling you neoprene chota owners feel!   $19 FF slop boots....$90 trekkers.   same ankle support.  i think i made a good decision.  and mine dont stink......much.   lol
