eban, I have the llbean breathable stocking foot. they "wicked" nice. They are really comfortable and have put in a lot of 6-8 hour days in them. I use the aquastealth boots. Equally as comfortable but I have run into a problem with them. I am going to be returning the boots, the stitching has come undone on the inseam of where the rubber sole meets the fabric on both boots.
BUT they do have a life time warrenty!!
