I regularly wear Danner SealSkinz over a pair of Smartwool socks when hiking in tall grass in the mountains here. I've never had a problem with sweaty or stinky feet with this combination and my feet are always warm and dry at the end of the day. I highly recommend the SealSkinz but those are the only ones I recommend; everything else I've tested has been crap, especially GoreTex. I also pack a couple pairs of SealSkinz for float trips in case of leaky waders (either from a puncture or in through the big hole at the top) during the trip or as loaners if someone goes for an unexpected swim. They do get damp inside after a couple of days so it's good to have a second set so that you can turn the first inside out to dry while wearing the second, but the Smartwools wick the dampness away from your feet so that you never feel it and it is just "damp" not "soaked".
