The Teva Sling King is a great low profile minimal water shoe that has great protection and traction when around or in the river.
The Water Mocassin is a neoprene 3mm sock with a Kevlar out-sole that rolls up around the foot for durability. Very compacted for tight fitting play boats. Great for short walks to a play park but not much protection for swims and hiking around.
Hope this helps...
