I live in sunny central California and hike and kayak quite a bit.  The fit on these is fine for me, and I always appreciate the Keen arch support, in fact that's why I buy Keens.  I also appreciate that they have a closed heel and toe, another reason to buy this particular style.  The problem with these?  The elastic laces loosen up on extended uphills and downhills, the neoprene stays wet a long time after you wade through water in them, and they smell bad soon after putting them on, despite washing with special "enzyme" neoprene cleaners.  The last is the killer; I've never had trouble with smelly shoes before, and don't want to start now, might lose my hiking buddies!  I'm going to try regular laces with them, but any ideas about cleaning these would be appreciated, I'd really like to keep using them.
