sadly, I think Nike is too big a company to care about the niche markets. They also had a canyoneering shoe, the Riovero, for a year or two that was awesome, awesome, awesome and gaining popularity amongst canyoneers, but its such a small market that I don't think Nike realized or cared that they were doing well in it because its such a small market.
Does Five Ten still make the water tennie?
How about the La Sportiva Exum River? Anyone tried this one for creeking? Its a canyoning shoe based on the Exum Ridge: uber-durable, grippy and fast-draining, but very lightwight and low profile. Unfortunately I am more familiar with canyoneering than creeking so I can't really say if it would be great for creeking. I would think, however, that if it fits in your creeker, then it would be awesome because they are very comfortable shoes, very light, drain well (made for walking in water) and the frixion rubber grip is as good as it gets for wet rocks.
