Merrell Water Pro - Muy Bueno. If you don't mind the low top action and possibly have a neoprene bootie or bootie from your dry suit (to keep you warm), these are extremely good choices. Great rubber, siped outsoles, tons of ways for the water to drain out. Straps will keep your kicks where they need to be, on your feet.
Teva Gamma Pro - Same idea as the Water Pro, not as well built but still gets the job done. Low top also and no insulation. Dirt gets in a little more than on the Water Pro.
Keen Hood River Boot - Sticky Rubber Outsole with built in drainage. Neoprene upper for warmth, dual straps to keep it on the foot. Mid height.
There are also 2 other versions of it - I'm always thinking Colorado conditions, but there are these as well:
Hood River Shoe
Hood River II
As for BOOTIES, Count, the P2 should not be considered a true creeking piece. It's a little minimal so far as retension, support, and safety go. There most certainly are good creeking booties such as the Tokatee and other high top booties with stiffened outsoles for walking, but I would caution against believing that a neoprene bootie is a creeking shoe. Hopefully something will come along to fill that gap between bootie and shoe soon. RyGuy, you working on anything?
