I have the water tennies and have maybe a dozen or so runs on them. Compared to the various brand of booties these have superior grip and are a lot more comfortable. Good ankle support too - I'd hike in them no problem.
They fit fine in the creeker - I know that is an issue sometimes, but I had no problems.
Yeah, they take a while to dry. I have boot dryers normally for skiing and just stick them in the dryers.
